Description
FULL PRODUCT VERSION :
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]
A DESCRIPTION OF THE PROBLEM :
When a class annotation is placed on a method definition, the following fatal error occurs:
com.sun.tools.doclets.internal.toolkit.util.DocletAbortException: java.lang.ClassCastException: com.sun.tools.javadoc.ClassDocImpl cannot be cast to com.sun.javadoc.MethodDoc
This should at best be a warning, and breaks backward compatibility with all previous JVM versions.
REGRESSION. Last worked in version 7u76
ADDITIONAL REGRESSION INFORMATION:
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Its a hard failure so ??? no idea what I am doing wrong or where
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Just display a warning rather than triggering a hard failure
ACTUAL -
com.sun.tools.doclets.internal.toolkit.util.DocletAbortException: java.lang.ClassCastException: com.sun.tools.javadoc.ClassDocImpl cannot be cast to com.sun.javadoc.MethodDoc
ERROR MESSAGES/STACK TRACES THAT OCCUR :
com.sun.tools.doclets.internal.toolkit.util.DocletAbortException: java.lang.ClassCastException: com.sun.tools.javadoc.ClassDocImpl cannot be cast to com.sun.javadoc.MethodDoc
*NO STACK TRACE* THIS MAKES THIS PRACTICALLY IMPOSSIBLE TO TRACK DOWN IN A LARGE PROJECT
REPRODUCIBILITY :
This bug can be reproduced always.

The place above is the only place in your code where a ClassCastException could possibly be wrapped within a DocletAbortException. Possibly wrapping in a Fault would at least report a stack trace?
---------- END SOURCE ----------
CUSTOMER SUBMITTED WORKAROUND :
Don't use JDK 1.8. It is impossible to change source code annotations in existing projects already in production at thousands of sites.
