#832 Error Encountered On Compilation

[Anonymous]

I encountered the error message (stack trace attached) on compiling my program in Dr.Java. Happens when I fix a couple of errors and attempt to recompile.

A new JVM release that reportedly fixes this bug has just become available at http://java.sun.com/javase/downloads/widget/jdk6.jsp. Download Java 6 Update 18 or newer and let us know if you solves your problem

This is a documented bug in Java 6 (not in DrJava), which is supposed be fixed very soon in a new JVM release.

See http://bugs.sun.com/view_bug.do?bug_id=6828938 and
http://bugs.sun.com/view_bug.do?bug_id=6857057.

In our experience, it does not adversely affect the behavior of Drjava so I ignore it. It happens often on Linux with the Plastic look-and-feel.
