FULL PRODUCT VERSION :
javac on apple box: 1.6.0_13
javac in windows box: 1.6.0_14 (latest at time of writing)

ADDITIONAL OS VERSION INFORMATION :
Tested on both mac os x with apple VM and windows with sun VM.
Apple box: Darwin hostname.local 9.7.0 Darwin Kernel Version 9.7.0: Tue Mar 31 22:52:17 PDT 2009; root:xnu-1228.12.14~1/RELEASE_I386 i386

A DESCRIPTION OF THE PROBLEM :
//Stuff the following snippet in a file and compile it:

//This code has been carefully distilled to be the simplest possible thing that causes
//the problem.

//Compiling this on javac 1.6.0_13 causes the following problem:
// annotation A is missing <clinit>

@interface A {
        //Compile time constants will NOT trigger the error, but 'null' is not a CTC.
        String B = null;
}

class C {
        private @A int d;
}


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile the code given in the description. Javac prints an error even though the code is valid.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The code should compile normally. To be specific, there *IS* a <clinit>, which you can see by compiling the @interface separately, and using javap to see that there's a static block that initializes the constant. Therefore, javac is erroneously reporting that the @interface has no <clinit>.

ACTUAL -
See "Error Messages".

ERROR MESSAGES/STACK TRACES THAT OCCUR :
foo.java:13: annotation A is missing <clinit>
private @A int d;
^
1 error



REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
@interface A {
        //Compile time constants will NOT trigger the error, but 'null' is not a CTC.
        String B = null;
}

class C {
        private @A int d;
}


---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Move the constants into another class.

Created an attachment (id=226) [details]
diff against jdk7-b147

With this fix <clinit> wont be treaten as a member when validating annotation
in
com.sun.tools.javac.comp.Check.validateAnnotation().
