I saw the announcement that Java 7u1 had fixed all the known bugs 
relating to Solr.  Is there anything I need to be aware of when 
upgrading?  These are the commandline switches I am using that apply 
to Java itself:


-Xms8192M
-Xmx8192M
-XX:NewSize=6144M
-XX:SurvivorRatio=4
-XX:+UseParNewGC
-XX:+UseConcMarkSweepGC
-XX:+CMSParallelRemarkEnabled


I assume from the lack of response that either there are no foreseeable 
problems or the potential problems are so bad that nobody wants to 
mention them.


I would upgrade to Java 7 on my secondary index servers first.  My SolrJ 
build program is normally colocated on one of the primary index servers, 
though corosync/pacemaker can move it in the event of a machine failure.


Here's a more targeted question:

In simple terms, this means that for a testing period of several weeks, 
my SolrJ application will be running a different Java version than one 
of my indexes, and the same version as the other index.  The Java 7 
announcement on the Solr page says that there are unicode changes when 
upgrading to Java 7.  Will those changes cause problems with SolrJ on 
one java version and the index on another?


Thanks,
Shawn

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,
