NPE when used with Pitest

[8armed-monkey]

The detail of the problem could be found here:
hcoles/pitest#345

A sample project where the issue occurs could be found here:
https://github.com/8armed-monkey/sample-npe-pitest-retrolambda

Class where the lambda is used:
test.event.EventBroadcasterImpl.java

The NPE doesn't occur if I change the lambda / method reference to anonymous inner classes (the Retrolambda plugin is still being used, but it doesn't create additional classes).

The ticket hints that this may be related to missing source file debug information. Retrolambda persists the lambda classes that Java 8 generates at runtime, and those classes are missing debug information. It might be possible to add debug information at least for the source file name.

I wonder if #130 is related.

This has been fixed in Retrolambda 2.5.3
