Scenario:
* two JPMS modules `org.foo.a` and `org.foo.b`, both with module-info
* `org.foo.a` requires `org.foo.b`
* `org.foo.b` exports package `org.foo.b.c`
* `org.foo.a` contains a text file: src/main/resources/org/foo/b/c/Foo.txt
* when surefire is run on module `org.foo.a` a dump file error occurs:
```
Corrupted STDOUT by directly writing to native stream in forked JVM 1. Stream 'Error occurred during initialization of boot layer'.
java.lang.IllegalArgumentException: Stream stdin corrupted. Expected comma after third character in command 'Error occurred during initialization of boot layer'.

Corrupted STDOUT by directly writing to native stream in forked JVM 1. Stream 'java.lang.module.ResolutionException: Module org.foo.a contains package org.foo.b.c, module org.foo.b exports package org.foo.b.c to org.foo.a'.
```
While the scenario is one that JPMS rejects, surefire should handle it better. The compiler compiles the code just fine because it doesn't see the resources as a package. Surefire is thus the first part of Maven that sees it as a "package" that clashes with the module org.foo.b.
Clearly, some part of surefire needs to be taught to about java.lang.module.ResolutionException, as the error is tricky to find/see because it is a dump file.

Research direction
Reproduce the JPMS scenario with modules org.foo.a and org.foo.b, then inspect org.apache.maven.plugin.surefire.booterclient.output.ForkClient around lines 209 and 511, where the reported stream corruption is handled. Done means the ResolutionException is surfaced clearly instead of being misreported as a corrupted dump-file stream.
