If you still want the above code to compile in compliance < 1.7, to mimic JDK 6 or below, you can use the system property tolerateIllegalAmbiguousVarargsInvocation to force Eclipse to tolerate such ambiguous varargs cases. This property can e.g. be set in the eclipse.ini file after the -vmargs setting:
...
-vmargs
-DtolerateIllegalAmbiguousVarargsInvocation=true
...Note: With this setting, Eclipse also mimics JDK 6 and below in raising an error in other cases that are legal in both JDK 7 and Eclipse:
- invalidJavadoc: set all warnings for malformed Javadoc tags
- invalidJavadocTag: validate Javadoc tag arguments
- invalidJavadocTagDep: validate deprecated references in Javadoc tag args
- invalidJavadocTagNotVisible: validate non-visible references in Javadoc tag args
- invalidJavadocVisibility(<visibility>): specify visibility modifier for malformed Javadoc tag warnings
- missingJavadocTags: enable detection of missing Javadoc tags
- missingJavadocTagsOverriding: detect missing Javadoc tags in overriding methods
- missingJavadocTagsMethod: detect missing Javadoc tags for method type parameter
- missingJavadocTagsVisibility(<visibility>): specify visibility modifier for missing Javadoc tags warnings
- missingJavadocComments: detect missing Javadoc comments
- missingJavadocCommentsOverriding: detect missing Javadoc tags in overriding methods
- missingJavadocCommentsVisibility(<visibility>): specify visibility modifier for missing Javadoc comments warnings
- nullAnnotConflict: detect conflict between null annotation specified and nullness inferred. Is effective only with nullAnnot option enabled
- nullAnnotRedundant: detect redundant specification of null annotation. Is effective only with nullAnnot option enabled
- nullUncheckedConversion: detect unchecked conversion from non-annotated type to @NonNull type. Is effective only with nullAnnot option enabled
- unusedParam: detect unused parameter
- unusedParamOverriding: detect unused parameter for overriding method
- unusedParamImplementing: detect unused parameter for implementing method
- unusedParamIncludeDoc: detect unused parameter documented in comment tag
- unusedThrownWhenOverriding: detect unused declared thrown exception in overriding method
- unusedThrownIncludeDocComment: detect unused declared thrown exception, documented in a comment tag
- unusedThrownExemptExceptionThrowable: detect unused declared thrown exception, exempt Exception and Throwable
