Description
FULL PRODUCT VERSION :
A DESCRIPTION OF THE PROBLEM :
interface A
{
abstract <T> void foo();
}
interface B
{
abstract void foo();
}
class C<T extends A & B>
{
void bar(T x)
{
x.foo();
}
}
javac throws the following exception:
java.lang.ClassCastException: com.sun.tools.javac.code.Type$MethodType cannot be cast to com.sun.tools.javac.code.Type$ForAll

This bug can be reproduced always.
Bugs 4851398 and 4881362 reported crash using similar conjunction types but those could not be reproduce.
This crashes same way with jdk5,6,7.
