Hi Bengt,
My code review for the rest of the files:
defNewGeneration.cpp:
517-520: Indentation
766: Shouldn't the tags be "gc, promotion"?
collectorPolicy.cpp:
489: Shouldn't the tags be "gc, heap"?
genCollectedHeap.cpp:
1150+1152: Indentation
generation.cpp:
162: Indentation
plab.cpp:
153: Plab_size = " SIZE_FORMAT " desired_net_plab_sz = " SIZE_FORMAT ":
Why the capital P in this printout of one variable name but not the
other? I think it should be consistent.
referenceProcessor.cpp:
515: Indentation
referenceProcessor.cpp:
948+953: Indentation
metaspace.cpp:
1505: Indentation
1578+1580: Indentation
2695: Indentation
runtimeService.cpp:
123-124: Indentation
Thanks,
David
