We are seeing intermittent SEGVs running specjbb2013 with both aarch64 jdk8 port (built from ssh://firstname.lastname@example.org/aarch64-port/jdk8u) and jdk9 (built from ssh://email@example.com/jdk9/hs-comp).
This crash only occurs on Partner X hardware.
Prebuilt binaries which exhibit the problem may be downloaded from
A sample hs_err log is attached below.
This only occurs with UseParallelGC so it happens by default with jdk8 but only happens with jdk9 with -XX:+UseParallelGC
The frequency of the crash is about one in 10 runs.
The command used to invoke specjbb2013 is
java -Xmx50g -Xms50g -Xmn40g -Dspecjbb.forkjoin.workers=48 -jar specjbb2013.jar -m COMPOSITE
(note: if using jdk9 you also need -XX:+UseParallelGC to observe the problem)
