Hi Uwe,

You must have been reading my mind. See inline....

Unfortunately as a Java programmer I am not so familiar with building the JVM on Ubuntu machines (including the needed IcedTea), so it's hard to me to try this out - I would not even know how to start doing this or finally how to get something like a standard JDK directory so you could use it as JAVA_HOME.

Use:  -XX:MarkStackSize=4M to increase the marking stack size in a 32 
bit run.

Otherwise we would need to wait until a new build appears on jdk8.java.net (including the fix + other fixes in javadoc/javac tool and the class library that we reported earlier).

I just sent you email. I downloaded a zip file that contains all the jar 
files. I don't have ant on my system so ideally I'm looking for a java 
command line to tickle the crash. Can you help?

Thanks,
