Description Achim Demelt

I kindly ask to backport bug #386187 (update tycho to use released Juno dependencies) to Tycho 0.15.x. The JDT version used in 0.15.0 appears to be from May 2, which happens to suffer from some bugs that have been fixed in time for the Juno release.

One of these bugs is bug #380927 (VerifyError issue with inconsistent stack map frames). This bug appears consistently when using Xtext in conjunction with Java 7. The problem now is that building and running Xtext plugins within Eclipse (Juno) and PDE Runtime works fine, but when everything is build on the CI server with Tycho, the old (buggy) version of JDT is used and users installing the plugins will see the "inconsistent stackmap frame" errors. See bug #389454 for an example.

There is nothing that we as Tycho users can do to work around this bug other than NOT using Tycho, which is obviously not an option...

Tycho 0.15 was released before Juno and used latest RC jdt compiler available at the time. Tycho 0.16 already uses jdt compiler 3.8.1.v20120531-0637, which I believe corresponds to final Juno version. There are no plans to release Tycho 0.15.x at this point, but even with current 0.15.0 you should be able to force the new jdt compiler version with plugin <dependency> element in your pom.xml file.
