Description

The Oracle JDK supports rolling over GC logs. I propose to add the following to the solr.in.

{sh,cmd}

scripts to enable it by default:

-XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=20M

Unfortunately, the JDK doesn't have any option to append to existing log instead of overwriting so the latest log is overwritten. Maybe we can have the bin/solr script roll that after the process is killed?
