EVALUATION This is not GC related (it happens with UseSerialGC too and actually there is no GC happening). It's reproducible on x64 with and without compressed oops. I can not reproduce it on x86 and SPARC though. $ gamma -XX:+UnlockExperimentalVMOptions -XX:+EnableInvokeDynamic -Xcomp -XX:-UseCompressedOops -cp /java/devtools/share/junit/latest/junit.jar:. org.junit.runner.JUnitCore test.java.dyn.MethodHandlesTest Without COOP: # SIGSEGV (0xb) at pc=0xfffffd7ffa467d00, pid=13059, tid=1 # # JRE version: 7.0-b119 # Java VM: OpenJDK 64-Bit Server VM (20.0-b03-internal-jvmg compiled mode solaris-amd64 ) # Problematic frame: # J java.util.Arrays$ArrayList.toArray()[Ljava/lang/Object; With COOP: # Internal Error (/home/ct232829/hotspot-comp/hotspot/src/share/vm/runtime/handles.cpp:46), pid=13073, tid=1 # assert(SharedSkipVerify || obj->is_oop()) failed: sanity check # # JRE version: 7.0-b119 # Java VM: OpenJDK 64-Bit Server VM (20.0-b03-internal-jvmg compiled mode solaris-amd64 compressed oops)
