      Description

        The test test\jdk\jdk\jfr\event\oldobject\TestHeapDeep.java tries to locate memory leaks in a small heap that consists of a linked list of 100 000 elements.The test passes, but it executes slowly, about 30 seconds instead of a few milliseconds.

        This is a product bug.
