      Description

      Looking a heap dump of 10GB, a large number of Configuration objects(> 66k instances) are being retained. These objects along with its retained set is occupying about 95% of the heap space. This leads to HMS crashes every few days.

      I will attach an exported snapshot from the eclipse MAT.
