  the regexp in the test is not correct for product mode, as the number
of references is not printed for JNI weak references there.

Line

  48       "#[0-9]+: \\[JNI Weak Reference, [0-9]+ refs, [0-9]+\\.[0-9]+
secs\\]");


should be

  48       "#[0-9]+: \\[JNI Weak Reference, [[0-9]+ refs, ]?[0-9]+\
\.[0-9]+ secs\\]");

I think to optionally match the number of refs for JNI weak references.
Otherwise one could make the regexp dependent on the build type it is
run (using Platform.isDebug()).

Thanks,
  Thomas
