------------------------------------

Hi Mark, Can you point out what are the issues when we use WriteAhead provenance repositoy with G1G1? We are using JDK 1.8.

> It is not recommended to use G1GC along with the Write-Ahead Provenance Repository due to known bugs in the G1GC in versions of Java earlier than 1.9. The default for the Provenance Repository was changed to the Write-Ahead Provenance Repository, but the garbage collector still defaults to G1GC.
