FULL PRODUCT VERSION :
java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Linux hendy.dev 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux


EXTRA RELEVANT SYSTEM CONFIGURATION :
Linux Mint 17 64-bit KDE

A DESCRIPTION OF THE PROBLEM :
When compiling code with invalid syntax for multiple annotations of @JsonSubTypes.Type (see sample code) generates the internal compiler error: java.lang.NullPointerException at com.sun.tools.javac.comp.Check$1AnnotationValidator.visitAnnotation(Check.java:2707).

Fixing the syntax of the code makes the compile successful. However, this syntax error case should be handled by the compiler by displaying appropriate error message.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create code with invalid multiple annotations syntax as described.
2. Compile
3. internal java compiler error


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Appropriate error message, e.g. "Cannot parse: Invalid multiple annotations syntax"
