Thanks for offering to help Aleksey, that's great!
Ive opened HARMONY-5313 and attached a script and a patch to be applied.
Please run the script before applying the patch, as one file needs to be
moved before it is patched. Once it's applied, if you run the
fetch-depends target you should see that the new ICU4J jars are
downloaded. Then if you just rebuild you should be ready to run with the
new version.
Thanks for the help!

Thanks, Oliver!
Performance data on microtests is looking good, however I wonder what
impact it has on DRLVM and large benchmarks. Haven't you filed JIRA
for this issue? If I'll have exact steps to build configuration with
new ICU, I could check it's performance before committing the changes
to the trunk.

Thanks Aleksey.
I have run the JUnit tests with the IBM VME and they pass without any
new failures. I have also run the encoding/decoding test in HARMONY-3709
a number of times - in general, ICU4J 3.8.1 performs in that test as
well or slightly better than the ICU4J 3.8 jar we are currently using. I
have attached the results of the latest run I made [1].

Good news, Oliver!
Anyway, basing on our previous experiences with ICU changes, we might
first try how Harmony performs with new ICU onboard before making this
change default. That's not only JUnit and other validation suites, but
performance too (say, Dacapo and other benchmarks performance).
Thanks,
Aleksey.

ICU 3.8.1 has just been released, so Id like to propose that after M4 we
upgrade to this release, add it to the fetch-depends target and remove
the "homemade" ICU4J jar we have stored in SVN.
Im running the tests with the new version now to make sure there are no
regressions and will be happy to make the required changes when the time
comes.
Objections?
Regards,
Oliver
