[oe] [meta-java] openjre-8: java from master/master-next crashes on startup

[Jacob Kroon]

Hi Richard,

I still can't use openjre-8 in either warrior, zeus or master builds, 
due to the crash below. I wonder, is anyone successfully using openjre-8 
in either of these releases ?

I see the crash both in my custom machine and in qemux86-64. If it makes 
a difference, I'm using

PREFERRED_PROVIDER_virtual/java-initial-native = "cacao-initial-native"
PREFERRED_PROVIDER_virtual/java-native = "cacao-native"

since building with jamvm has always been broken for me.

Any hints ?

Cheers,
Jacob
