ShutdownHooks causing heap memory overflow [message #1863444]

I am using jgit 6.6.1, before that I was using jgit 6.3.0. After upgrading the version I am facing the issue of HeapSpaceError. I am running a java application which will run continuously.
Runtime.getRuntime().addShutdownHook(cleanupHook);
This will keep adding cleanupHooks in ApplicationShutdownHooks, but as application or JVM is not getting close this will increase the heap size utilization.

So, what is the solution for such application which will continuously running.

I am currently using JGit version 6.6.1, having recently upgraded from version 6.3.0. Since the upgrade, I have been encountering Heap Space Errors in my Java application, which runs continuously.
The issue appears to be related to the addition of cleanup hooks in the ApplicationShutdownHooks. I have noticed that in upgraded version of JGit new PidLock with lock() method was introduced in jgit.internal.storage.file.GC class. As of my knowledge ApllicationShutdownHooks execute the hooks at the time of application or JVM closing but in our case it will not happen as application need to be run continuously, which lead to continuous insertion of hooks in ApplicationShutdown hooks and causing heap space error after some time.

Update to the latest release or master, this should contain the fix.
