RE: [JENKINS-EA] Lucene-Solr-trunk-Linux (64bit/jdk-9-ea+105) - Build # 15928 - Failure!

[Uwe Schindler]

Hi,

I played around. I am quite sure this was a hotspot issue (maybe the same one 
Robert has analyzed). I asked java.lang.invoke to dump all bytecodes to disk 
and inspected them. The code calling Runnable interface was always correct 
after disassembling. I have no idea what else could be wrong, we should just 
watch this.

Uwe
