The tier1_common seems to be quite specific test group. It contains mostly testing that ignores vm flags. It doesn't make any sense to run the with VM flags. While from other point it has all non-component tests that should be executed in tier1. 

So it is enough to run this groups once.  While in all testing after tier1 the group hotspot_misc should be used instead.
