Hi Evgeniya

What about LoadWithMask.java test?

Please, simple remove '-server' option. We always do testing with server JVM so we can't miss the bug if it returns. We 
did go through such cleanup in tests before and did not have any problems.

Flag -XX:-TieredCompilation may affect bug reproduction. That is why we specify it sometimes.
In general we can remove it too since we run Nightly in both configurations with and without Tiered. But since it does 
not affect what JVM is used we keep it.

In compiler tests we should not specify neither -server or -client to make sure the correct JVM is tested. This is one 
of our rules when we add tests. Recently we added tests which have -server specified:


compiler/stable/* test have  @run command with both -server and -client configurations.

All these tests should be cleaned up.
