Description

BCEL throws the ArrayIndexOutOfBoundsException when trying to construct a new org.apache.bcel.generic.MethodGen on a method containing the bytes compiled from the following code:

switch {
case Integer.MAX_VALUE:
break;
default:
b = true;
}

The method that does not handle this corner case correctly is org.apache.bcel.generic.TABLESWITCH.initFromFile(ByteSequence, boolean).
