AnnotatedElementUtils.findMergedAnnotation not working for javax annotations (e.g. NotNull) #22957
Description
Affects: 5.1.x
Meta-annotations not being scanned for any package that begins with the "java" string, which includes the javax package.
The utility the method AnnotationUtils.hasPlainJavaAnnotationsOnly is checking if the class name starts with "java" instead of "java."
Previously using AnnotatedElementUtils.findMergedAnnotation we could have an element annotated with javax.validation.constraints.NotNull search for the meta-annotation javax.validation.Constraint However, this stopped working with 5.1.x because it relies on the utility method.
Excluding all packages which begin with the string "java" and not targeting known and specific packages is a big assumption.
