Description

Solr should use the -XX:+DisableExplicitGC option as part of its default GC tuning.

None of Solr's stock code uses explicit GCs, so that option will have no effect on most installs. The effective result of this is that if somebody adds custom code to Solr and THAT code does an explicit GC, it won't be allowed to function.

---

Update: Based on the discussion in the JIRA, adding ExplicitGCInvokesConcurrent option instead DisableExplicitGC so that jcmd, jvisualvm could be run
