I played around with Java 8 ea b72, but I get a compiler error. Is there a way to get more information from javac, e.g. the file list it is currently working on? If I had a general idea where to look I might be able to find a work-around until the issue is fixed.

Just for the record, here is the stack-trace (it looks similar if compiled outside of IntelliJ IDEA, BTW):

An exception has occurred in the compiler (1.8.0-ea). 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.

Have you tried javac’s -verbose flag? A simple ant script such as the following could be used to enable verbose compiler output,

<project name="verbose_compile" default="compile" basedir=".">
  ...
  <target name="compile">
      <javac srcdir="${src.dir}" 
         destdir="${build.dir}"
         executable="${java8.home}/bin/javac" 
         classpath="..."
         fork="true" 
         verbose="true" />
  </target>
</project>

(Looks like user property maven.compiler.verbose would accomplish the same thing in maven.)

I just ran into a similar situation. On Windows, the verbose output showed me the class being compiled just before the error. Hopefully that will help you narrow down the problem for a workaround.
