In the NB trunk:
Warning - could not install some modules:
J2EE Server Registry - The module named
com.sun.tools.j2ee.editor/1 was needed and not found.
The module is named
Name change in manifest.mf to org.netbeans.libs.j2eeeditor/1 committed
I guess this one is fixed (j2eeserver/manifest.mf rev.1.20). Please
update the bug report next time.
