DGC and UseParallelOldGC

[Rainer Jung]

Hi all,

if I activate the parallel stop the world collector using
-XX:+UseParallelOldGC and DGC kicks in: will it run with multiple
threads in parallel, or will it only run single-threaded?

I know that in case I use CMS, there are ExplicitGCInvokesConcurrent and
ExplicitGCInvokesConcurrentAndUnloadsClasses which also influence DGC,
but I didn't find any info about the situation using parallel old GC.

TIA!

Regards,

Rainer
