Comments
[~stefank]: okay, thanks, I will close this one then. The other also mentions that this causes a crash, so they seem equivalent.

[~tschatzl] I wanted to notify you about the duplication, but didn't want to take the decision about which of the bug reports to close. Erik is working on JDK-8224674, while this talks about the crash. Therefore I left it up to triage and/or Erik to decide how to proceed.

[~stefank]: can you close this as Duplicate, not only link it as duplicate if it is a duplicate?
