I had the same problem trying to run a scala program with Ubuntu 10.4 and stock eclipse (Galileo 3.5.2) and java (java-6-openJdk ) - and the scala pluging downloaded from scala site, of course. I fixed it by manually changing /usr/lib/eclipse/plugins/com.ibm.icu_4.0.1.v20100125.jar as suggested in this thread (btw I discovered that Emacs can change a jar file in place: nice):

It's caused by ubuntu openjdk package with broken symbol links for TimeZone configuration. The best solution from forum thread is,

<blockquote>
 Reinstalling tzdata-java was the fix for me:

<pre><code>sudo apt-get --reinstall install tzdata-java

The problem is:

A quick google search reveals that this class belongs to the IBM Globalization package ICU. <a href="http://www-01.ibm.com/software/globalization/icu/index.jsp" rel="nofollow noreferrer">http://www-01.ibm.com/software/globalization/icu/index.jsp</a>

A guess would be that this is a package used internally by Scala that you have not installed properly, causing Scala startup to fail.

Make sure that you set java 1.6 in the run configuration (Run/Run configurations).

blocks|key|3100728|text|你升级到雪豹了吗？您使用的是Eclipse+SWT/Carbon还是Eclipse+SWT/Cocoa？在我升级到SL之后，我发现Eclipse有一些奇怪的地方。从Eclipse+SWT/Carbon切换到Eclipse+SWT/Cocoa很有帮助。我还恢复了我的1.5虚拟机，SL安装以一种偷偷摸摸的方式删除了它(通过删除并保留指向1.6的符号链接)，帮助我修复了本机Java代码的几个问题(即usb串行端口代码)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3100729|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Did you upgrade to Snow Leopard? Are you using the Eclipse SWT/Carbon or the Eclipse SWT/Cocoa? I was seeing some strangeness with Eclipse after I upgraded to SL. Switching to the Eclipse SWT/Cocoa from Eclipse SWT/Carbon helped. Also restoring my 1.5 VM, which the SL install removes in a sneaky way(by deleting and leaving the symbolic link pointing to 1.6), helped me fix several issues with Java code that had natives(i.e. usb-serial port code).

blocks|key|2172123|text|检查Eclipse知道的JVM是什么，以及它们位于何处(Preferences+->+Java+->+Installed+JRE)，并检查程序的运行/调试配置。默认情况下，Eclipse知道用于启动自身的JRE，以及您手动添加的其他JRE。但是，如果您升级了一些组件，而JRE发生了变化，Eclipse可能会对它们感到“困惑”。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2172124|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Check what are the JVMs that Eclipse is aware of and where they are located (Preferences -> Java -> Installed JRE), and also check the run/debug configuration of your programs. By default, Eclipse knows about the JRE that was used to launch itself, and other JREs that you add manually. However, if you upgrade some components and the JREs changed, Eclipse can get "confused" about them.

blocks|key|5214546|text|我在Windows上使用Eclipse时也遇到了同样的问题。我尝试了许多不同的方法，包括在新的工作空间中使用新的hello+world程序。通过将Eclipse指向另一个要执行的JRE，我终于让它正常工作了。我知道Apple为Mac提供了JRE，但这个问题看起来确实与Eclipse本身运行的JRE有问题有关。有关配置执行here的VM的信息，请参阅Eclipse。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5214547|entityMap|0|LINK|mutability|MUTABLE|url|http://wiki.eclipse.org/FAQ_How_do_I_run_Eclipse%253F#Find_the_JRE^0|4H|4|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I had this same issue with Eclipse on Windows. I tried a number of different things including a new hello world program in a new workspace. I finally got this to work by pointing Eclipse to a different JRE to execute with. I know that Apple provides the JRE for Mac, but it does seem like this issue is related to Eclipse having trouble with the JRE used to run Eclipse itself. See <a href="http://wiki.eclipse.org/FAQ_How_do_I_run_Eclipse%3F#Find_the_JRE" rel="nofollow noreferrer">here</a> for configuring which VM Eclipse executes with.

I'm trying to get started with Eclipse/Java/Scala on a MacBook. The installed JDK was 1.5. The SDT plugin for Scala requires 1.6 which was included in an OS update, but I also manually installed a package from Apple to update 1.6.
The problem is that I cannot run anything from Eclipse. I always get the following error:

<code>
An internal error occurred during: "Launching TestFooBasicTest".
Could not initialize class com.ibm.icu.impl.JavaTimeZone
</code>

I also tried to use the old 1.5 version, but to no avail.

What is going wrong here?

我正在尝试在MacBook上开始使用Eclipse/Java/Scala。安装的JDK是1.5。Scala的SDT插件需要1.6，它包含在操作系统更新中，但我也手动安装了Apple的一个包来更新1.6。问题是我不能从Eclipse运行任何东西。我总是得到以下错误：An internal error occurred during: "Launching TestFooBasicTest". Cou
