Validate 2.4.0/3.0.0 fail with NPE/internal error on certain test cases

[jpl-jengelke]

🐛 Describe the bug identified during I&T

Execute validate -t testdata/badtype.xml against the linked dataset used to test pds4-im#499. This will yield both an exception and an internal error. (See attached output, Also, please note an earlier SNAPSHOT of Validate 2.4.0 did not yield this error but the current releases do.)

This error only manifests on this test case so far as others currently appear to not yield the error.

I wonder if my fix for validate#544 would also solve this 🤔

Unfortunately we are still seeing the issue with v3.0.2 release.
