[OpenJDK 2D-Dev] RFR: JDK-8218682 + JDK-8198411: [TEST_BUG] DashOffset fails in mach5 + Two java2d tests are unstable in mach5

[Phil Race]

can you add
@key headful

to all these tests ?

I think that the isHeadless() test was not catching the case when some 
VM is in use
that really should not have run the test.
The fix is still valid but I think we should have this too. This way 
jtreg won't bother even
running the test if there's no head.
