public int getCatchType() {
		return catchType & 0xffff;
	}
If the value of the catch_type item is nonzero, it must be a valid index
into the constant_pool table. The constant_pool entry at that index
must be a CONSTANT_Class_info (?4.4.1) structure representing a class of
exceptions that this exception handler is designated to catch. The exception
handler will be called only if the thrown exception is an instance of the
given class or one of its subclasses.
<p>
If the value of the catch_type item is zero, this exception handler is called
for all exceptions. This is used to implement finally (?3.13).
@return the value of the catch_type item
