The changes to RowClosure.java looks good!

these tests were added to jdk/test/ProblemList.txt as part of [0]. Could
you please remove the tests from jdk/test/ProblemList.txt as part of
this change?

The changes to the tests looks good.

Please be aware of that the tests are only failing on 32-bit platforms.
If you want to reproduce them easily locally, the fastest way I found
was to add -XX:-UseCompressedClassPointers in the tests (they do not
take the -vmoption argument to jtreg into account).

Thanks,
Erik
