Hi

I svn upped today (actually saw this few days ago too), and ran 'ant clean'.
Then from lucene/contrib/benchmark I ran 'ant compile' and hit this:

    [javac] An exception has occurred in the compiler (1.5.0). 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.
    [javac] java.lang.AssertionError: {unused}

BUILD FAILED

This only happened w/ IBM Java 5, and didn't happen w/ Sun's 5 or IBM/Sun's
6. I've found this related;
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6297416. Searched the
code for "unused" suppresses and found TestPositionIncrement had this
pattern. So I've committed this to trunk (doesn't happen on 3x 'cause the
Suppress isn't there):

     }

BTW, the Suppress was not necessary because the byte[] is used in the print.

FYI in case you run into it one day :).
