Hi
Could you please review following fix which removes
vmTestbase/gc/gctests/Steal tests from the repo.
These tests might fail provoking OutOfMemoryError throwing it in
unexpected place. The logic and intention of these tests are very
unclear from their description and code.
Test allocate objects till OOME. Than test removes some references ans
start allocate objects provoking OOME and corresponding GC. It doesn't
clear how it should stress taskqueue work-stealing in GC better than any
other test causing a lot of GC.
This test however mentioned in a couple of bugs where crashes were
caused by OOME in Heap.
https://bugs.openjdk.java.net/browse/JDK-8180627
https://bugs.openjdk.java.net/browse/JDK-8130344
Assuming that we already have enough tests stressing OOME and tests
stressing GC. I think it makes sense just to remove these two tests.
I verified that they are not in any jtreg group.
