IDEA cannot compile source code with JDK 6 beta 2 build 78

Hello t800t8,

looks like you've found a bug in Mustang latest javac. AFAIK they've changed
lots of code in b78, so it is likely to cause exceptions.
I'd rather file that one to them.

Eugene.

When I try to compile my source code, I got this error:

Information:An exception has occurred in the compiler (1.6.0-beta2).
Please file a bug at the Java Developer Connection
(http://java.sun.com/webapps/bugreport) after checking the Bug Parade
for duplicates. Include your program and the following diagnostic in
your report. Thank you.
