Bug 340000

Comment 1 Ralf Sternberg 2011-03-15 10:27:35 EDT

Built M6 with icu.base 4.2.1 again as this version is known to work, we should upgrade for M7.

Comment 2 Holger Staudacher 2011-04-26 06:02:36 EDT

I checked the original eclipse.ui bundles and these bundle don't have a version constraint in their mainfests for icu.base. So, I removed the contraint from our manifests and committed the changes to CVS HEAD.

Sadly our tests are failing when we use the new icu.base version. Here is the stack trace. For now I will not update the icu.base version on our build server until we can figure out why this error happens.

In version 4.4.2 they changed the execution environment to 1.5 - see com.ibm.icu_4.4.2.v20110208.jar manifest.mf. It was 1.3 in com.ibm.icu_4.2.1.v20100412.

Comment 4 Ralf Sternberg 2011-05-04 06:25:53 EDT

Since icu has been upgraded to Java 1.5, we have to keep the old icu.base in our target platform for the 1.4 release.
We removed the version ranges from our bundle manifests, as the platform bundles do so as well.
Starting with RAP 1.5, we'd like to move to Java 1.5 too (bug 344334), so we can fix this issue in the next release.

* All Up to the last RAP 1.4 service release, icu.base version 4.2.1 is used.
* In RAP 1.5, we upgraded to J2SE-1.5 and use the current icu.base version from the platform again (4.4.2).
* Since the package imports are unversioned in the original bundles, I'll leave them unversioned in the RAP bundles as well.
