Does anyone have any information on upgrading to Java7 with Solr?  Any 
gotchas, recommendations, or should I just go for it without changing 
anything?  Java6 goes EOL in November, after which public (free) support 
and bugfixes go away.  By then running Solr with Java 7 will be 
important to the entire community, not just me.

Thanks,
