Description Moritz Eysholdt CLA 2011-11-30 05:06:47 EST 
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.
Comment 1 Holger Schill CLA 2011-11-30 13:09:10 EST 
pushed fix and tests to master
Comment 2 Sebastian Zarnekow CLA 2011-12-01 05:28:08 EST 
It's ok to write something along those lines:

def doStuff() throws IOException, FileNotFoundException {
}
Comment 3 Holger Schill CLA 2011-12-01 05:35:23 EST 
removed the validation for subtypes and corresponding tests. pushed to master
