Adding that cured that crash, but the new HeapDumpCompressedTest test failed due to lack of a backport of [JDK-8233790](https://bugs.openjdk.java.net/browse/JDK-8233790). 8233790 guarantees that the "Unable to create" string for which the test checks will be in the output file. That backport looks useful to me, so I'd do it as a pre-req to this one.

Hi Paul, thank you for pointing out the lack of line 258, I will fix it and update the patch. I know JDK-8233790 is a fix for the HeapDumpCompressedTest, I will backport it after this patch merge.
