During work on JDK-8049130 for creation of golden files for negative tests, it was discovered that the error messages reported for tools/javac/annotations/repeatingAnnotations/UseWrongRepeatable.java were 'almost similar'.

Error keys reported:
UseWrongRepeatable.java:17:1: compiler.err.invalid.repeatable.annotation.value.return: java.lang.annotation.Target, java.lang.annotation.ElementType[], UseWrongRepeatable[]
UseWrongRepeatable.java:17:21: compiler.err.invalid.repeatable.annotation.value.return: java.lang.annotation.Target, java.lang.annotation.ElementType[], UseWrongRepeatable[]
UseWrongRepeatable.java:14:1: compiler.err.invalid.repeatable.annotation.value.return: java.lang.annotation.Target, java.lang.annotation.ElementType[], UseWrongRepeatable[]


As confirmed by Joel, error messages in line 17 are duplicate and can be improved. Error message as reported in line 14 should stay.
