Limit garbage collector to one thread

[1-alex98]

Those need to be added to Intelij conf(edit run configuration) as well as the install4j(just search for the other options in the install4j configuration that is on top level) one.

For Java 8 there are another options which depends on OS. You could see them for Windows here. Some you could find helpful:

    -XX:CICompilerCount=threads Sets the number of compiler threads to use for compilation
    -XX:ConcGCThreads=threads Sets the number of threads used for concurrent GC. The default value depends on the number of CPUs available to the JVM (!possible cause of your problem!)
    -XX:ParallelGCThreads=threads Sets the number of threads used for parallel garbage collection in the young and old generations. The default value depends on the number of CPUs available to the JVM
    -XX:+UseParNewGC Enables the use of parallel threads for collection in the young generation. By default, this option is disabled (but it could be enabled due to another options)
