I tried to upgrade from M4 to jbosstools-3.3_stable_branch.aggregate-Update-2011-12-09_00-34-40-H51 which I downloaded from http://downloads.jboss.org/jbosstools/builds/nightly/core/3.3.indigo/2011-12-09_00-34-40-H51/all. However, I got 2 problems:
a) The targeted runtime of an EJB project is visible, but the according JARs are NOT appended to the classpath resp. buildpath.
b) In a utility project I cannot add the server library although the server itself is configured.

I'll attach 3 screenshots:
1) 1_M4_ok shows the regular behavior when using M4.
2) 2_M5_targeted_runtime_not_in_classpath shows that the server runtime is configured, but the according jars are not part of the buildpath in an ejb project.
3) 3_M5_no_selectable_runtime_for_utility_project shows that adding a server library doesn't work because the configured server runtime is not listed.
