Finished: FAILURE






Attached is a screenshot of the Abstract Class causing the failure. Using an Interface works correctly but requires me to repeat the code for `publishProject` in each concrete implementation of the Abstract Class Flow which is not ideal.

Research direction

Start by reproducing the Global Shared Library failure with an abstract class and inspect the CpsTransformer.groovy locations named in the stack trace, especially loc and makeChildren. Compare the semantic-analysis and canonicalization paths to determine where the null lineNumber originates; done means the reproducer no longer fails with the reported NullPointerException and the behavior is covered by a regression test.
