Fix ClassCastException for @PrepareForTest(fullyQualifiedNames = "...")#983
Merged
Conversation
Add an `instanceof J.NewArray` check before casting the assignment value in `extractPrepareForTestClasses`, so `@PrepareForTest(fullyQualifiedNames = "...")` with a string literal no longer crashes the recipe.
ClassCastException for @PrepareForTest(fullyQualifiedNames = "...")
…cted
Filter the `J.NewArray` initializers to class references only and skip the
annotation-removal scheduling when nothing was extracted, so usages such as
`@PrepareForTest(fullyQualifiedNames = "...")` or
`@PrepareForTest(fullyQualifiedNames = {"a","b"})` leave the source intact
instead of stripping an annotation the recipe cannot migrate.
