Error messages are usually way longer than the start/stop, deploy dialogs. Not sure if the dialogs are implemented by J2EE server or the individual plugin. Anyway, the error messages tend to be weird too, for example, they have spaces before full stops and things like that.
MartinA is going to look at it.
Fixed. Diff: http://j2eeserver.netbeans.org/source/browse/j2eeserver/src/org/netbeans/modules/j2ee/deployment/impl/ui/ProgressUI.java.diff?r1=1.6&r2=1.7
