http://194.25.240.197:9980/chart.memory.leak.7z

on Produktion system i use an intervall from 1 minute and 1gb
the oom is throws after 6 days

REGRESSION. Last worked in version 8u112

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Start the programm
-Xmx100m
-XX:+HeapDumpOnOutOfMemoryError

lanuch visual vm
sample memory with "java.lang.ref"

wait
after seconds an OutOfmemory is throws


REPRODUCIBILITY :
This bug can be reproduced always.
