Many thanks Volker, I am on vacation now but I will put it the top of my todo list.

Merry Christmas and a happy new year to you too ��

Hi Martin,

I've just pushed the fix to jdk8u/jdk8u-dev [1] so it should be in the next regular 8u update (probably 8u172 ?).

You can of course test it any time by building the tip of http://hg.openjdk.java.net/jdk8u/jdk8u-dev yourself :)

Merry Christmas and a happy new year,
Volker
