Hi,

please review the following patch:
https://bugs.openjdk.java.net/browse/JDK-8184669
http://cr.openjdk.java.net/~thartmann/valhalla/vt_prototype/webrev.31/

Escape analysis gets confused because the Klass input of a ReturnNode is tagged (since JDK-8183546 [1]) and therefore a ConLNode instead of a KlassNode is found.

Thanks,
Tobias
