Trouble running ES on Java7 with G1 Garbagecollect

We have experienced JVM-crashes when using the G1 garbagecollection on java
7
(-XX:+UseG1GC)

We are running ES 0.20.6

A fatal error has been detected by the Java Runtime Environment:

SIGSEGV (0xb) at pc=0x00007f84f5198de8, pid=21673, tid=140204359747328

JRE version: 7.0_25-b15

Java VM: Java HotSpot(TM) 64-Bit Server VM (23.25-b01 mixed mode

linux-amd64 compressed oops)

Problematic frame:

J

org.elasticsearch.common.trove.impl.hash.TObjectHash.insertKey(Ljava/lang/Object;)I

Is this a known issue?
