I have a problem when trying to compile using the meghanada-server:

It seems like the problem arises from:

meghanada-server/src/main/java/meghanada/analyze/TreeAnalyzer.java

Line 1543 in 507f400

String className = currentClass.get().name;

Where there is no check for if currentClass has a value.

Is this a bug in the implementation, or is it me who are using the tool wrong?
