G1 GC issues
------------

                 Key: HBASE-2039
                 URL: https://issues.apache.org/jira/browse/HBASE-2039
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: stack


Lets keep an issue where we report on g1 issues.  Lets keep list of crashes we see.

I filed an issue up on bug parade.  Lets see if it becomes actual bug.  Below I note version
of vm and the type of crash (Internal Error (nmethod.cpp:1981), pid=32319..... Its a 'fatal
error').  It happens for me after 5-10 minutes when a loading test.  Same thing each time.

G1 in 1.6 seems plain broke; crashes on use of stuff in concurrent utils package.
