Hi JDT team, Would you please check it? Thanks.
Per bug 338033 you need to update either the scala IDE or AJDT that you are using. The equinox weaving you those products are using is out of date and leading to this issue. Per comment 5 in the bug I referenced: === Try updating to the latest snapshot of Equinox Weaving available from the AJDT update sites here: for Indigo http://download.eclipse.org/tools/ajdt/37/dev/update or for Juno http://download.eclipse.org/tools/ajdt/42/dev/update All you need to update is the Equinox Weaving feature. Hopefully, this will fix the problem. === *** This bug has been marked as a duplicate of bug 338033 ***
