Description Moritz Eysholdt

Example:

---
class foo  {
	def bar() throws IOException, IOException, Exception {
	}
}
---

I'd expect IOException to get a validation error because of two reasons:
- It's declared twice
- Is a subtype of Exception, therefore declaring "Exception" alone should be sufficient.


However, for Java, the JDT flags neither of those issues.

pushed fix and tests to master

It's ok to write something along those lines:

def doStuff() throws IOException, FileNotFoundException {
}

Comment 3 Holger Schill

removed the validation for subtypes and corresponding tests. pushed to master
