@jankratochvil thanks for the update. I guess even if some method now doesn't return null, we'd be better prepared if it starts in future due to some refactoring.

Can see that the recent change failed jcheck

Check failure on line 808 in src/com/sun/javatest/TRT_TreeNode.java
openjdk / jcheck

Whitespace error

Column 50: trailing whitespace



Once jcheck is OK, I guess we might be good to go to resolve the issues you are facing with a parallel run
