Sijie Guo updated BOOKKEEPER-563:
---------------------------------
Attachment: BOOKKEEPER-563.reverse.diff
simply reverse the diff file using patchutils :
interdiff BOOKKEEPER-563.diff /dev/null > BOOKKEEPER-563.reverse.diff
> "os.name" checking.
I think the OS check here is necessary. I am assuming someone would run it in
windows platform.
> Avoid Journal polluting page cache
