[transformer-dev] Transformation failing ..

[Amit Pande <amit.mypict@xxxxxxxxx>]

Hello all,

Was trying to use the Eclipse Transformer to transform the javax namespace to jakarta namespace. Ran into below issue:

----------------------

main] ERROR Transformer - Unexpected failure
java.lang.NullPointerException
        at java.base/java.util.Objects.requireNonNull(Unknown Source)

Attaching the files to reproduce this issue.

Ran below command -

java -jar org.eclipse.transformer.cli-0.5.0.jar   test/com/myorg/test/CheckCaseValidator.class test/com/myorg/test/CheckCaseValidator.class.transformed

Kindly let me know what I am missing.

Our project base is relatively large and hence running the Eclipse Transformer is going to be immensely helpful.

Really appreciate your help.

Thanks,

Amit
