<br>
ParallelGC summarizes liveness information (among other things)
into<br>
regions for parallel compaction. It allows the calculation of the
region<br>
index for the region just beyond the end of the heap but should
not<br>
access that region. One of the printing methods mistakenly did.<br>
<br>
One line fix + more detail on a couple of the asserts + a test<br>
<br>

<br>
Tested with new test and with gc_test_suite (in progress) and
-Xlog:all=trace.<br>
<br>
Thanks.<br>
