Patch fixing JDK-8176553

[Jan Kalina]

Hi,
I has prepared trivial patch for bug JDK-8176553, which I has reported.

I will welcome if it could be merged into JDK.
(The bug is present in JDK9 and JDK8 too.)
I am covered by Red Hat OCA.

The patch is attached, bug reproducer is already in JIRA:
https://bugs.openjdk.java.net/browse/JDK-8176553

Thanks,
Jan Kalina
