What should I do when a NullPointer Exception occurs? Print

First, make sure that the Java project under examination does not have any compilation errors and all the required external jar libraries are included in the Java Build Path of the project (project Properties -> Java Build Path -> Libraries). Such exceptions occur when the AST parser attempts to resolve AST bindings from library class types which are not included in the build path of the examined project.

If the exception persists (after fixing the compilation errors), then you are welcome to send the produced error log to tsantalis`at ' gmail dot com
