Ukuthintela iingxaki zomthetho ngeOracle (ephethe ulwandiso lobunini), cangakumbi nangakumbi iinkampani zizakhela eyazo iJDK isuka kwi-OpenJDK kwaye izuze uluntu ngomsebenzi wabo.
Nokuba yiRed Hat, iAmazon phakathi kwabanye, ukubala ezimbalwa, Zonke ezi nkampani zineeJDK zazo. Ngokutsho kwabo, i-Oracle's proprietary extensions itshabalalisa ukuzithemba kwabaphuhlisi abahamba ngokuthe ngcembe bevela kulwimi lweJava.
UAlibaba Dragonwell
IJava lulwimi olusetyenziswa ngokubanzi kwiAlibaba njengoko ifuna i-JDK elungiselelwe usetyenziso lwayo ezorhwebo, ezemali, kunye neenkonzo zokuhanjiswa kweintanethi ezisebenza ngaphezulu kweeseva ze-100,000.

IAlibaba Dragonwell yinjini eqhuba izicelo zethu zeJava ezisasazekayo, ”utshilo iqela.
Iqela leAlibaba Dragonwell linika ingxelo yokuba le yokugqibela iqinisekisiwe ngokuhambelana nomgangatho weJava SE kwaye ingxelo yangoku iyahambelana kuphela neqonga leLinux yolwakhiwo lweX86 kunye neX64.
Ngaphandle kokuba yimfoloko ye-OpenJDK, inezinye izinto inkampani ezijonga njengezibaluleke kakhulu emsebenzini wayo.
"Ngokwamkela i-OpenJDK ukuqhuba usetyenziso lwethu, siye saqonda isidingo sokwenza ngokwezifiso ngokuthe ngqo ukuthunyelwa kwesicelo esikhulu seJava," iqela labhala.
Malunga neAlibaba Dragonwell 8.0 New Version

- Kukhethwe inketho entsha encinci kwi-dump subcommand yesixhobo sokulahla ukungahoyi imixholo yoluhlu lwangaphambili lwe-heapdump.
- Njengokhetho olutsha PrintaYoungGenHistoAfterParNewGC ukuprinta i-histogram yezinto emva kweParNew GC.
- Inketho yePrintaGCRootsTraceTime yongezwa ukuze kuprintwe iinkcukacha zeParNew GC njengeG1GC. Nceda abasebenzisi ukuba bafumane ingxaki yexesha elide lokuphumla. Inokuvulwa / ivalwe ngujinfo
Kwaye inketho entsha yeArrayAllocationWarningSize yokuprinta isitaki seminxeba yoluhlu olungaphezulu kweArrayAllocationWarningSize. Ixabiso elingagqibekanga lolu khetho luyi-512M. Oku kungatshintshwa nguJinfo.
