- I-Java 27 manje isiyatholakala ngokujwayelekile ngama-JEP ayisishiyagalolunye, kufaka phakathi i-TLS yangemva kwe-quantum kanye ne-G1 njengomqoqi kadoti ozenzakalelayo.
- Ama-header ezinto ezihlangene aba yindinganiso, okunciphisa kakhulu i-memory overhead yezindawo ezinkulu ze-Java.
- I-Oracle iphinde ithumele izibuyekezo eziqondile ze-Helidon 27, i-JavaFX 27, kanye ne-Jipher 20, kanye nokubuka kwasekuqaleni kwe-Project Valhalla.
I-Oracle ikhiphe ngokusemthethweni i-Java 27, inguqulo yakamuva yolimi lokuhlela kanye neplatifomu yokuthuthukiswa esebenze isikhathi eside, okuphawula esinye isinyathelo ekuguqukeni kweplatifomu ngale komjikelezo wendabuko we-LTS. Lokhu kubuyekezwa, okufinyelele ukutholakala okuvamile ngoSepthemba 15, kuletha inhlanganisela yezici ezilungele ukukhiqizwa kanye nokubuka kuqala okuhlose ukwenza i-Java isebenze kahle, iphephe kakhudlwana, futhi ilungele kangcono inkathi ezayo ye-quantum computing. Lokhu kukhishwa kuyinguqulo yesibili engeyona i-LTS kusukela ku-JDK 25 , futhi ifaka iziphakamiso eziyisishiyagalolunye ze-JDK Enhancement Proposals (JEPs) kuphakheji i-Oracle eyichaza njengesisekelo esizinzile kokubili imisebenzi yamanje yebhizinisi kanye nezinhlelo zesikhathi esizayo eziqhutshwa yi-AI.
Kwabathuthukisi, izinguquko zesihloko zimayelana nokuzenzakalelayo: i-G1 garbage collector manje isetshenziswa kuzo zonke izindawo, ama-compact object headers avuliwe ngokuzenzakalelayo, futhi indlela entsha yokushintshanisa ukhiye we-post-quantum ingeziwe ku-TLS 1.3. Lawa akuwona ama-API amasha akhanyayo kodwa kunalokho athuthukisa i-under-the-hood anciphisa ukulandelwa kwememori, enze lula ukucushwa, futhi aqinise ukubethela ngokumelene nezinsongo zesikhathi esizayo. Ukukhishwa kufaka phakathi nokubuka kuqala izici ezifana ne-concurrency ehlelekile kanye nama-constant avilaphayo, okubonisa ukuthi ipulatifomu iya kuphi emijikelezweni embalwa ezayo.
Ama-JEP ayisishiyagalolunye: Yini Ekhona Ebhokisini Ngempela
I-Java 27 iletha ama-JEP ayisishiyagalolunye, amane awo abhekwa njengalungele ukusetshenziswa ekukhiqizweni. Amanye amahlanu asesesigabeni sokubuka kuqala noma sokukhulisa , okunikeza abathuthukisi ithuba lokubuka amakhono azayo ngaphandle kokuzibophezela kuwo ekukhiqizweni. Phakathi kwezinto ezilungele ukukhiqizwa, i-JEP 523 yenza umqoqi weGarbage-First (G1) abe ngokuzenzakalelayo kuyo yonke indawo, ethatha indawo yomqoqi we-Serial ezindaweni ezivinjiwe. Ngokusho kwethimba le-OpenJDK, i-G1 ithuthuke ngokwanele ekusetshenzisweni kwe-throughput, i-latency, kanye nememori ukuze iphathe ngisho nosayizi omncane we-heap, okususa isidingo sokuba abathuthukisi bakhethe ngesandla umqoqi ohlukile kumadivayisi anememori ephansi.
Olunye ushintsho olubalulekile yi-JEP 534, evumela ama-compact object headers ngokuzenzakalelayo. Lokhu kunciphisa i-memory overhead yento ngayinye ye-Java kusuka kuma-bits angu-96 kuya kuma-bits angu-64, ushintsho olungaletha ukonga okunenjongo kuzo zonke izigidi zezinto eziphilayo. Kuma-benchmarks e-SPECjbb2015, ukushintsha kuholele ekunciphiseni okungu-22% kokusetshenziswa kwe-heap kanye nokwehla okungu-8% kwesikhathi se-CPU, ngokusho kwemibiko. I-Amazon ne-SAP sezivele zamukele lesi sici ekusakazweni kwazo kwe-Java, okubonisa ukuthi sizinzile ngokwanele ukusetshenziswa kwangempela.
I-Cryptography Yangemva Kwe-Quantum Ithatha Isigaba Esiphambili
Ukuphepha kungathiwa yisihloko esikhulu kunazo zonke seJava 27. I-JEP 527 yethula ukushintshaniswa kokhiye we-post-quantum hybrid we-TLS 1.3, ihlanganisa i-algorithm ekhona ye-ECDHE nendlela ye-NIST-standardized ML-KEM post-quantum. Lokhu kubhekana nemodeli yokusongela ethi "vuna manje, susa ukubethela kamuva" , lapho abahlaseli begcina khona ithrafikhi ebethelwe namuhla ngethemba lokuyiphula uma amakhompyutha e-quantum esenamandla ngokwanele. Indlela ye-hybrid isho ukuthi akukho zinguquko zekhodi ezidingekayo kumakhasimende namaseva e-TLS ajwayelekile, okwenza kube ukuthuthukiswa okungenabuhlungu ezinhlanganweni ezikhathazekile ngokugcinwa kwemfihlo kwedatha yesikhathi eside.
I-Oracle iphinde iqhubekele phambili phambili kwe-cryptographic nge-JEP 538, ukubuka kuqala kwesithathu kwe-PEM encodings yezinto ze-cryptographic, kanye ne-JEP 536, enezela ukuhlelwa kwedatha okusenqubo ku-Java Flight Recorder. Lokhu kokugcina kuwusizo kakhulu ekuxazululeni izinkinga zokukhiqiza , njengoba kususa ulwazi olubucayi ekuxilongweni ngaphambi kokuba lubhalwe kudiski, kusiza izinkampani ukuhlangabezana nezidingo zokuthobela imithetho.
Izibuyekezo Zesistimu Yezinto Eziphilayo: I-Helidon, i-JavaFX, kanye ne-Jipher
Kanye nesikhathi sokusebenza esiyinhloko seJava, i-Oracle imemezele izibuyekezo ezihambisanayo ezingxenyeni eziningana ezibalulekile ze-Java Verified Portfolio yayo (JVP). I-Helidon 27, uhlaka lwe-microservices, manje ilandela uhlelo olufanayo lokuguqula njenge-OpenJDK futhi yethula ukwesekwa kwezintambo ezibonakalayo kanye nama-Scoped Values, okwenza kube lula ukubhala izinsizakalo ze-cloud-native ezihambisana kakhulu. I-JavaFX 27 iletha ipayipi elisha lokunikeza i-Metal ku-macOS ukuze isebenze kahle ku-Apple silicon, kanye nezici zokuphatha izithombe ze-JavaFX ezithuthukisiwe kanye nokufinyeleleka. I-Oracle Jipher 20, umhlinzeki we-cryptographic oqinisekisiwe we-FIPS 140-3, manje usefakiwe ku-JVP futhi wengeza ukwesekwa kwama-algorithms e-ML-KEM kanye ne-ML-DSA post-quantum.
Lezi zibuyekezo ziyingxenye yesu elibanzi lokugcina i-Java ecosystem ihlangene, ikakhulukazi njengoba amabhizinisi asebenzisa ubuchwepheshe be-AI kanye ne-cloud. Ukukhishwa kufaka phakathi ukubuka kuqala kwe-Project Valhalla ngokusebenzisa i-JDK 28 early access, okuhlose ukuvala igebe phakathi kwezinto nezinto zokuqala ngezigaba zenani—isici esingathuthukisa kakhulu ukuminyana kwedatha yokuhlaziya kanye nemisebenzi ye-AI.
Lokhu Kusho Ukuthini Kubathuthukisi
Kumaqembu asebenzisa i-Java ekukhiqizweni, indlela yokuthuthukisa ilula kakhulu. I-Oracle ichaza i-Java 27 njengendlela yokufaka esikhundleni sezinhlelo zokusebenza ezikhona ngaphandle kokuthi zithembele kuzici zokubuka kuqala. Iqoqo elisha likadoti elizenzakalelayo kanye nama-compact headers aklanyelwe ukusebenza ngaphandle kokushintsha kwefulegi, okusho ukuthi izinhlelo zokusebenza eziningi kufanele zibone ukusebenza okuthuthukisiwe kanye nokusetshenziswa kwememori okuncishisiwe ngemuva kokuthuthukisa. Kodwa-ke, ukushintshaniswa kokhiye we-post-quantum kuvunyelwe kuphela ukuxhumana kwe-TLS 1.3 , ngakho-ke amaphrothokholi amadala ngeke azuze ngaphandle kokushintsha kokucushwa.
I-Oracle iphinde yabonisa izinhlelo zokushintshela ku-cadence yanyanga zonke yama-patches okuphepha abalulekile, kanti isibuyekezo sokuqala esinjalo kulindeleke kamuva kulo nyaka. Lolo shintsho luzonikeza izinhlangano ukufinyelela okusheshayo ekulungisweni kobuthakathaka, kodwa futhi kusho amafasitela okulungisa avame kakhulu. Okwamanje, i-Java 27 inikeza inhlanganisela eqinile yentuthuko okufanele ikhange kokubili amabhizinisi kanye nabathuthukisi ngabanye, noma ngabe izici ezijabulisa kakhulu zisesezindaweni ezimbalwa ezikhishwe.
Konke lokhu kuza njengoba i-Oracle iqhubeka nokusunduza iJava ibheke esikhathini esizayo esilawulwa yi-AI kanye nezinsongo ze-quantum. Ukuhlanganiswa kwe-cryptography ye-post-quantum, okuzenzakalelayo okungcono, kanye nokulungiswa kwe-ecosystem kubonisa ukuthi ipulatifomu iyathuthuka ukuze ihlangabezane nezidingo zengqalasizinda yesimanje. Nakuba iJava 27 ingase ingabi ukukhishwa okuguqula ikhodi yansuku zonke, ibeka isisekelo sezinguquko ezinkulu ezifika nge-JDK 28 nangale kwalokho.
