Jdeveloper installation folder size increasing beyond limit , Reason was hprof (Heap Profiling) files

Recently i faced a problem, i was lacking space on my C drive so  checked all directories and found that the size of Jdeveloper 12.1.3 installation folder Oracle-->Middleware  was approx 30 GB . This is not expected as Jdev. takes approx 1.5 to 2 GB space only

Then i found some java_pidXXXX.hprof file that was taking lot of space in this folder
