Description

If a blueprint application has classes that have constructors that throw multiple exceptions, such as:

public MyClass(String something) throws IllegalStateException, NumberFormatException {
...

The ASM Method.getMethod(String) call fails with a StringIndexOutOfBoundsException.

It's not 100% clear from the ASM method Javadoc, but I suspect that it's not expecting any throws declaration in the string passed in.

The problem occurs in ProxySubclassAdapter.visit when it tried to get the constructor, and although there is a Method.getMethod(Constructor) method, this returns a different return value (method name is always "<init>"), which still doesn't work.

So, the rather inelegant solution appears to be to strip off the exceptions from the method string.

Diff will be attached.
