Compressed oops failure with hs19 master

[Vladimir Kozlov]

Andrew,

I looked on 647737 and reports were against HS19b06 but
Oracle even not officially released jdk6u23 which has HS19.
As one note in 647737 pointed, current build of HS19 is b09
so I would suggest to try it (it is not clear if it was done).
And if it will not help, you may disable compressed oops
in your build. Also it would be nice to have a small
test which shows the problem.
We are testing COOP for long time already but most likely
when 6u23 will be out we will find some issues which
our testing did not catch.

thanks,
Vladimir
