Java on ALPHA

[papa]

I knew that ALPHA had Java installed, but previous attempts to compile a small hello program terminated with the error, "Unable to initialize threads: cannot find class java/lang/Thread".

Today I looked up that error message and discovered that it's caused by not having CLASSPATH set, so I entered the following command and tried compiling again:

$ define java$classpath .,sys$common:[java$131.lib]tools.jar,sys$common[java$131.lib]dt.jar,sys$common:[java$131.jre.lib]rt.jar

Now JAVAC starts, but terminates with the following output:

End of JAVAC output ========================

Looking up "SIGBUS 10* bus error", I find no definite solution, but learned that our Java (version 1.1.8-5) is VERY old. Any chance we could install a newer version?
