java - Show the default value choosen for XX:ParallelGCThreads -


this question has answer here:

i'm tuning jvm of java 8 , i'm trying know value defined parameter -xx:parallelgcthreads. documentation says:

-xx:parallelgcthreads: sets number of threads used during parallel phases of garbage collectors. default value varies platform on jvm running.

i know value defined in platform , if need change that. don't have in environment jdk, jre.

default value :

 java -xx:+printflagsfinal | grep parallelgcthreads  uint  parallelgcthreads                        = 4

if have running process jinfo <processid>, if it's not present in output, using default value (look under vm flags)
