对于桌面和应用程序，是否有 Sun 的 JVM 的可靠替代品？企业发展？
随着 Oracle 方面最近的发布，我们已经开始制定一项计划，逐步淘汰从 Sun JVM 迁移到我们最终将获得的任何可靠且免费的替代方案。
Open JDK 显然将成为一个主要选择，既然 IBM 已经宣布将重点关注它，但在稳定性和可靠性方面，它需要一段时间才能成为 Sun 现有 JVM 的替代品。
是否有任何 JVM 选项可以为现实生活中的关键任务应用程序提供支持？据我所知，IBM 的 JVM 只能在 IBM 硬件上使用。
如果您知道任何可以帮助我们描绘 JVM 领域图景的替代方案，我们将非常感谢您的反馈。
我们在 Eclipse 生态系统上进行了大量工作，并由 jboss 应用程序服务器提供支持，并且我们非常有兴趣了解我们的选择，因为访问 Oracle 的 JVM 可能需要许可费用。
With the recent announcements from Oracle side, we have started to work on a plan for phasing out migration from the Sun JVM to the whatever reliable and free alternative we will end up with.
Open JDK will obviously become a major option, now that IBM has announced its focus on it, but it will take some time for that to be an alternative to Sun's existing JVMs, in terms of stability and reliability.
Are there any JVM options out there, which are powering real life mission critical applications? IBM's JVM can't be used on other than IBM hardware as far as I know.
If you know of any alternatives which may help us depict a picture of the JVM domain, your feedback would be much appreciated.
We have large work on Eclipse ecosystems, backed up with jboss application servers and we're really interested in knowing our options now that access to Oracle's JVM is likely to require licencing fees.

IBM 的 JDK 在 x86 和 x86-64 处理器上的 Linux 上运行（已在 SuSE 和 Red Hat 上进行了测试）。我不认为它仅限于 IBM 硬件；我不认为它必须是 390 上虚拟化的 Linux。
但是，我完全不知道非 IBM 平台上是否支持它。如果您计划在生产中使用它，您可能需要某种支持协议，即使只是为了让客户满意。
IBM's JDK runs on Linux (it's tested on SuSE and Red Hat) on x86 and x86-64 processors. I don't believe it's restricted to IBM hardware; i don't think it has to be a Linux virtualized on a 390.
However, i have absolutely no idea whether support is available for it on non-IBM platforms. If you're planning to use it in production, you will probably need a support agreement of some sort, even if it's just to keep the suits happy.
如果有帮助的话，我现在在生产中运行 OpenJDK，它非常稳定。 （我最初运行的是 Sun JVM，但有一个迟来的错误导致我的应用程序崩溃，所以我不得不切换。）
If it is any help, I run OpenJDK in production now, it's been pretty stable. (I was originally running Sun JVM, but there is a long-overdue bug that was crashing my app, so I had to switch.)
您可以从他们的网站下载 IBM JVM。问题实际上在于支持以及您的环境中是否有 IBM 产品（IBM JVM 支持与其他产品捆绑在一起）。
IBM JVM 具有 Sun JVM 所没有的增强功能，例如 128 位加密和增强的 JavaEE 功能。阅读本文以了解其 mods - http:// domino.research.ibm.com/tchjr/journalindex.nsf/600cc5649e2871db852568150060213c/7d71c18820edabeb85256bfa00685e4b!OpenDocument
You can download the IBM JVM off their website. The question is really around support and whether you have IBM products in your env (IBM JVM support comes bundled with another product).
The IBM JVM has enhancements that the Sun JVM doesn't have like 128bit encryption, and enhanced JavaEE features. Read this paper to get an understanding of their mods - http://domino.research.ibm.com/tchjr/journalindex.nsf/600cc5649e2871db852568150060213c/7d71c18820edabeb85256bfa00685e4b!OpenDocument
尝试 JRokit。预计这将是最快的。
Try JRokit. It is expected to be the fastest one.
