Robin,
I am trying to run SemiSpace collector. It seems something inside MMTk was
moved but not all the regression tests were run?? I get the following stack
trace:
Uncaught exception in main:
java.lang.NullPointerException
at org.apache.HarmonyDRLVM.mm.mmtk.Assert.fail(Unknown Source)

at TestSemiSpace.singleRootTest(Unknown Source)

utility/alloc/BumpPointer contains the following:
protected void reusePages(int pages) {
VM.assertions.fail("Subclasses that reuse regions must override this
method.");
}
