[java] Parse error on rare extra dimensions on method return type on annotation methods

[oowekyala]

Affects PMD Version: 6.40.0

Make sure, to test with the latest PMD version.

Description: title. Found in checkstyle sources in #3640

Code Sample demonstrating the issue:

@interface Foo {
    String v1()[]; // parse error
    // equivalent to String[] v1();
}

Interesting: the eclipse compiler also shows an parse error... but it seems to be valid java code...

This is fixed in PMD 7.0.0-rc1. It won't be backported to PMD 6.
