sun.reflect.annotation.EnumConstantNotPresentExceptionProxy at runtime

[Gili T.]

Hi,

I am using Checkers versin 1.6.4 using the Maven plugin under JDK 7 update 40. At compile-time I get warnings about missing Annotation enums, such as:

  unknown enum constant java.lang.annotation.ElementType.TYPE_USE

At runtime, I get this exceptions which cause my unit test to fail:

I looked up the enum in question and sure enough it was only added in JDK 8. Does this mean that I cannot safely use Checkers Framework with JDK 7? The only way I can think of fixing this is producing a backported version of Checkers that does not use any JDK8-specific code.

Thank you,

Gili

Hi Gili,

all the Java 8 additions that are needed at runtime are included in
checkers/binary/javac.jar.
Make sure to include javac.jar on your bootclasspath and things should work.

Hi Werner,

I am fairly certain this is something that needs to be fixed inside
your Maven plugin code. I don't think this is something that can be
configure externally. Should I open a bug report?

Gili-

If you think this is the problem, then yes, please open a bug report. If
you give us a reproducible test case, that will help us help you.

Thanks a lot for the bug reports!

-Mike
