It looks like this issue is unique to 8u and I'm happy for the proposed patch to testme.sh to go into 8u under 8271466.

It looks like the solution here is a rewrite:

https://bugs.openjdk.java.net/browse/JDK-8240604

This would need to be backported to 11u first.

There is a series of bugs already that fix this and can be backported: JDK-8164322, JDK-8209011 & JDK-8267721
I was already looking at these when I saw JDK-8267721 appear in 11u, so will handle these backports.

Please flag JDK-8271466 with jdk8u-fix-request for approval. Do you need a sponsor to push the StackGap change?
