Description Carsten Reckord

2017-05-11 07:18:41 EDT

Sometimes, e.g. in crash logs, I only have class names like org.eclipse.swtbot.swt.finder.widgets.AbstractSWTBot$13 to go by in order to find the problem source. 

This is not a problem for top-level classes, where I can just open the type by name. It's a lot more difficult to open inner classes this way though. For named inner classes, I can either search by simple name, or if that's to common, use the FQN in dot-notation (e.g. java.util.Map.Entry). java.util.Map$Entry, as usually encountered in logs, does not work.

For anonymous classes, this doesn't work at all: neither org.eclipse.swtbot.swt.finder.widgets.AbstractSWTBot.13 nor org.eclipse.swtbot.swt.finder.widgets.AbstractSWTBot$13 gives a match. 

This makes navigating to these types a real pain. I propose to extend "Open Type" to support
- $-notation in addition to dot-notation for nested classes
- opening anonymous classes by their FQN

(Additionally, I think it would be nice to support qualified names without the package component, as often seen for named inner classes, e.g. "Map.Entry". But that might be worth a separate issue)
