> Could I have a review of this patch?
> 
> In the current implementation, HeapDumpBeforeFullGC/AfterFullGC will generate dumps for every FGC, increasing the risk of disk full.
> 
> This patch introduces a new option 'FullGCHeapDumpLimit' to limit the number of dumps triggered by HeapDumpBeforeFullGC/AfterFullGC to enhance production-friendliness.
