A DESCRIPTION OF THE PROBLEM :
For the given Test.java source file, javac crashes with an assertion error:
```
> javac -Xdiags:verbose -XDdev -J-XX:+ShowMessageBoxOnError Test.java
Test.java:10: error: cannot find symbol

An exception has occurred in the compiler (23-ea). Please file a bug against the Java compiler via the Java bug reporting page (https://bugreport.java.com) after checking the Bug Database (https://bugs.java.com) for duplicates. Include your program, the following diagnostic, and the parameters passed to the Java compiler in your report. Thank you.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile Test.java as shown above.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No crash.
ACTUAL -
With the diagnostic flags passed you see a stack trace. Without them, you still see a message "printing javac parameters to [path]", indicating a crash occurred.
