Hi Leonardo,

yes, we should strive to fix these things.
it would be even better if we can detect them earlier, by having a 
jenkins ppc slave to the ovirt jenkins, or just a local jenkins by you 
which will report when a patch breaks on ppc/ibm jdk for further 
consideration).

questions:
1. is there a bug right now to fix? we need the build to know to add the 
modifier when using ibm jdk.

2. (added alon) i remember we actually have an issue with ibm jdk wrt 
certificates or something which is worth considering in this context.

3. do you have more details on the openjdk performance issue on ppc to 
try and fix that one? can you open a bug on this and forward to us?

Thanks,
    Itamar
