0) JSR 45
1) Create an Xtend file A.xtend with a class X.
2) Export as Jar including source
3) Add the jar to the class path

Expand the jar in the package explorer and find X.class. Double click X.class and see that A.xtend is opened properly. 

4) Set a break point in A.xtend and run some main class that invokes the code
5) JDTs source lookup reports that A.xtend cannot be found

Possible solution:

Hijack the RuntimeProcess in the DebugListener and attach another SourceLookupParticipant to the SourceLookupDirector that knows how to handle Xtend types similar to what is done for types that share the name of the class.
