I have a few of the following warnings outputted by javac:

aaa.class: warning: Cannot find annotation method 'xxx()' in type 'yyyy': class file for fully.qualified.ClassName not found

However, they are not being picked up by the Warnings plug-in. I assume it is because they don't have the typical format of "[javac] file: warning: [type] message" (as the [type] part is not there).
