AnnotationUtils won't find javax annotations [SPR-17495]

[spring-projects-issues]

Phil Webb opened SPR-17495 and commented

Given a class Foo annotated with javax.transaction.Transactional calling:

AnnotatedElementUtils.getMergedAnnotation(Foo.class, javax.interceptor.InterceptorBinding.class)

Will result in null despite the fact that Transactional is meta-annotated with InterceptorBinding.

The root cause appears to be AnnotationUtils.hasPlainJavaAnnotationsOnly which does name.startsWith("java") and perhaps should do name.startsWith("java.").

spring-framework/spring-core/src/main/java/org/springframework/core/annotation/AnnotationUtils.java

Line 953 in b960368

return (name.startsWith("java") || name.startsWith("org.springframework.lang."));

Not loading javax types appears to be intentional and changing the logic is likely to degrade performance. Since we've added a guard in the Spring Boot code, I think we should close this one for now.
