Hi Martin,

Thanks for providing the reference.

In this particular case, it helped me to discover that 13 JVM threads 
were garbage collecting in parallel, occasionally resulting in a race 
condition. Setting

     options(java.parameters = "-XS:ParallelGCThreads=1")

appears to resolve the issue.
