Description

If you take the original testcase from MJAVADOC-555 and run it under JDK 12 you will get a new error message: "error: not in a module on the module source path"

I trust that MJAVADOC-555 fixed a bug under JDK 11 because the MJAVADOC-555_aggr_mixed integration test was failing before and is now passing, but it looks like we need a separate integration test for JDK 12.

I am attaching an updated testcase for the problem I am seeing under JDK 12.

Repro steps:

1. Open the attached testcase
2. Run mvn clean javadoc:aggregate
3. Build will fail with: error: not in a module on the module source path
