Subject [jira] [Commented] (HBASE-6945) Compilation errors when using non-Sun JDKs to build HBase-0.94
Date Wed, 19 Dec 2012 06:31:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6945?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13535712#comment-13535712
] 

Lars Hofhansl commented on HBASE-6945:
--------------------------------------

Some minor comments:
* Do we need to create the JVM object every time, or can be cache it statically like we did
with osStats?
* After the new JVM() the null check is unnecessary.
* in runUnixMXBeanMethod, do can we cache the outcome of classForName (even when that is null),
so that we do not have to make this call each time?

Maybe these are not problems, because this is not a hot code path?
