RFR: 8212008: Use of TREAT_EXIT_CODE_1_AS_0 hide problems with jtreg Java

[Christian Tornqvist]

Hi,

When running JDK and Hotspot jtreg tests through make, TREAT_EXIT_CODE_1_AS_0 is set to true. Any issue with the Java installation used to run jtreg won’t be reflected in the exit code. This has been seen a bunch of times in our internal CI system where we thought we ran tests but instead no tests were run at all because the jtreg Java installation had been deleted/corrupted.
