Oracle JDK vs OpenJDK

OpenJDK是Sun在2006年末把Java开源而形成的项目,这里的“开源”是通常意义上的源码开放形式,即源码是可被复用的,例如IcedTea、UltraViolet都是从OpenJDK源码衍生出的发行版。 Oracle JDK采用了商业实现,而OpenJDK使用的是开源的FreeType。当然,“相同”是建立在两者共有的组件基础上的,Oracle JDK中还会存在一些Open JDK没有的、商用闭源的功能,例如从JRockit移植改造而来的Java Flight Recorder。预计以后JRockit的MissionControl移植到HotSpot之后,也会以Oracle JDK专有、闭源的形式提供。 Oracle的项目发布经理Joe Darcy在OSCON 2011上对两者关系的介绍也证实了OpenJDK 7和Oracle JDK 7在程序上是非常接近的,两者共用了大量相同的代码(如下图,注意图中提示了两者共同代码的占比要远高于图形上看到的比例),所以我们编译的OpenJDK,基本上可以认为性能、功能和执行逻辑上都和官方的Oracle JDK是一致的。 OpenJDK和JDK区别 https://www.cnblogs.com/straybirds/p/8746532.html 在大多数LINUX发行版本里,内置或者通过软件源安装的JDK,都是安装的OpenJDK, 一

问题 Is IcedTea's Java browser plugin (OpenJDK browser java plugin) for windows available? I googled, but couldn't find any windows installer for the same. I tried Zulu, but it seems zulu is not providing browser plugin for Java. 回答1: IcedTea-Web devs provide binary builds at http://icedtea.wildebeest.org/download/icedtea-web-binaries. Click on the lastest version you can see, go to windows and there will be MSI and ZIP builds. It works well with Zulu 8(u202) for Windows from my experience, and

Play Framework causing SIGSEGV fault on first page load with crud moduel

我怕爱的太早我们不能终老 提交于 2019-12-24 06:40:32
问题 Found this bug, which states the problem as well as I could. https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/732707 The question is - are there any potential workarounds? Thanks 回答1: In the bug report they mention they use IcedTea JVM, not Oracle's one. I've never had this problem with Oracle's, so the workaround: use Oracle's JVM. Also, if you are using version 1.1.1 you should be aware there is a huge security hole, you should update to 1.2.3 ASAP. (latest 1.1.x may have it fixed,

Does this applet work in an Iced Tea JRE?

问题 I mentioned a small demo. in Setting up policies for an Applet embedded in HTML & an Iced Tea JRE user commented that the demo. failed for them. They refused permission to the applet (thereby limiting it to the sand-box) & were supposed to see the green colored 'this applet is sand-boxed' page. Instead the applet completely failed and they saw a 'gray space' where the applet should have been. I am WAGing that it was attempting to instantiate a File object that is the difference. I.E. The Sun
