rajeshbabu commented on HBASE-10533:
------------------------------------

bq.  Seems good to commit.
I too feel the same [~lhofhansl]. The fix will work properly with JRuby version 1.6.8 which we are giving in our releases.

With other versions of JRuby the first part of fix may not work(HBASE-9211). Not even this hbase shell starting if self fail with JRuby 1.7.0.

ping [~saint.ack@gmail.com],[~jdcryans],[~matteobanerjee]
Is it ok to commit or do we need to handle issues with other JRuby versions?
