JGit 5.3.7.202002110540-r adds - new WindowCache metrics - and enables using strong references to reference cache pages in the WindowCache. Set core.packedGitUseStrongRefs = true to enable using strong references to reference packfile pages cached in the WindowCache. If this option is set Java gc can no longer flush the WindowCache to free memory if the used heap comes close to the maximum heap size. On the other hand this provides more predictable performance. Documentation of core.packedGitUseStrongRefs is added in I895369a85, which will reach stable-3.0 by merge later. Change-Id: I8c080a16e25678dc6aeec9c21a6029965fb1ac5b
