Obviously I did not run the test to it's completion to get a jcov report before; my bad. :-(

However, when I'm now trying to run some more comprehensive testing with jcov, I get multiple test failures. Most are along the lines of:


STDERR:
[Jstatd-Thread] Picked up JAVA_TOOL_OPTIONS: -Xms64m -Xmx4g
[Jstatd-Thread] Picked up _JAVA_OPTIONS: -Xms64m -Xmx4g
[Jstatd-Thread] WARNING: jstatd is deprecated and will be removed in a future release.
java.lang.RuntimeException: Output does not match the pattern
Picked up JAVA_TOOL_OPTIONS: -Xms64m -Xmx4g: expected true, was false
        at jdk.test.lib.Asserts.fail(Asserts.java:715)


JAVA_TOOL_OPTIONS and _JAVA_OPTIONS are setup in lines 127...130 in RunTests.gmk. 

@mrserb  Is this expected behavior, or am I doing something wrong?
