"AIM:
Auto generate UML diagrams such as Class diagrams, Sequence diagrams from the existing Java code.

STEPS:
1/ I have installed Papyrus Software Designer 2.1.0 in Eclipse 2022-03.
2/ Selected a project with no submodules (I mean, the src folder is directly under the project folder).
3/ Created *.di file
4/ Selected SequenceDiagram.
5/ Dragged App.java from the <project>/<src> folder.
6/ An error message is shown 'Reverse Java Code' has encountered a problem "NullPointerException java.lang.NullPointerException"

QUERY: Why is this error thrown? Does Papyrus Software Designer supports Reverse Engineering (Java code to UML diagram auto-generation)?"

Papyrus SW Designer supports Java reverse engineering, but this support is limited to structural aspects. It does not support the creation of a sequence diagram. However, it should not throw an exception.
