Expensive GC Remark Phase for JNI Weak Reference

Using: - JDK 1.8u40 - UseG1GC, ParallelRefProcEnabled, Xmx12g,Xms12g - Solr 4.10.4 When using G1GC we are seeing very high processing times in the GC Remark phase during reference processing. Originally we saw high times during WeakReference processing but adding"-XX:+ParallelRefProcEnabled" flag
