Koert Kuipers 9b4173fa95 [SPARK-33894][SQL] Change visibility of private case classes in mllib to avoid runtime compilation errors with Scala 2.13 ... ### What changes were proposed in this pull request? Change visibility modifier of two case classes defined inside objects in mllib from private to private[OuterClass] ### Why are the changes needed? Without this change when running tests for Scala 2.13 you get runtime code generation errors. These errors look like this: ``` [info] Cause: java.util.concurrent.ExecutionException: org.codehaus.commons.compiler.CompileException: File 'generated.java', Line 73, Column 65: failed to compile: org.codehaus.commons.compiler.CompileException: File 'generated.java', Line 73, Column 65: No applicable constructor/method found for zero actual parameters; candidates are: "public java.lang.String org.apache.spark.ml.feature.Word2VecModel$Data.word()" ``` ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Existing tests now pass for Scala 2.13 Closes #31018 from koertkuipers/feat-visibility-scala213.
