@ -38,6 +38,9 @@ The test checks that after different type of GC unreachable objects behave as ex
non-humongous and humongous objects are not collected since we make 2 Young GC to promote all
weak references to Old Gen.
6. Mixed GC - weakly referenced non-humongous and humongous objects are collected, softly referenced non-humongous and
humongous objects are not collected.
The test gets gc type as a command line argument.
Then the test allocates object graph in heap (currently testing scenarios are pre-generated and stored in
TestcaseData.getPregeneratedTestcases()) with TestObjectGraphAfterGC::allocateObjectGraph.
