RFR: 8225644: [TESTBUG] langtools/tools/javac/generics/inference/8058199/T8058199.java fails with -Xcomp

[Joe Darcy]

Hi Jie,

To a first approximation, javac's output should predictably rely in its 
inputs. In other words, the output of javac, and by extension the 
success or failure of one its regression tests, should be independent of 
running under a particular HotSpot mode/configuration.

If test success/failure is dependent on a mode or configuration, I would 
suggest eliminating a VM issue as a cause before looking to update the test.

HTH,

-Joe
