What OS are you using?  Any Error (as opposed to Exception) is bad news,
and usually something wrong with the JVM or the machine.  Do other
applications (Java and non-Java) have problems on the system?

If it's RedHat Linux 7.0, there are some known issues with JDK 1.3.
There have been a few postings about how to fix it (see the mail
archives), but I've found the simplest was to disable the HotSpot VM.
In Ant, you can define to use the "classic" compiler as opposed to the
"modern", which is the default for 1.3 VMs.  If other Java apps have
similar problems, consider changing it system-wide.  Look around
${JAVA_HOME}/lib/jre/java.cnf (?), I think.
