Description
FULL PRODUCT VERSION :
java -version
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

javac -version
javac 1.8.0_25


ADDITIONAL OS VERSION INFORMATION :
OS X El Capitain ver 10.11.2

EXTRA RELEVANT SYSTEM CONFIGURATION :
IntelliJ IDEA 15 CE

A DESCRIPTION OF THE PROBLEM :
When I write fizzbuzz programming, error occured.(at compile time. via IntelliJ IDEA 'gradle test')


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I tried to writing joke programming.

1. make two classes(FizzException extends RuntimeException implements AutoCloseable, BuzzException extends RuntimeException implements AutoCloseable)
2. create static method below:

public static AutoCloseable make(int i) {
        try {
            // Any processing(no specific feature)
            throwFizzOrBuzz(i);
        } catch(FizzException | BuzzException e) {e){
            return (AutoCloseable) e;
        }
        throw new IllegalStateException();
    }

3.gradle build

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
build success.
ACTUAL -
java.lang.ClassCastException: com.sun.tools.javac.code.Type$UnionClassType cannot be cast to com.sun.tools.javac.code.Type$IntersectionClassType

CUSTOMER SUBMITTED WORKAROUND :
refactor multi-catch.

            return (AutoCloseable) e;
        }catch(BuzzException e) {
            return (AutoCloseable) e;
