Description Maxime Daniel CLA 2008-05-30 06:56:33 EDT 
v_871

On GenericTypeTest#1149, eclipse compiles OK while javac (1.5 to 7) fail.

Source:
public class A {
    <T extends Throwable> A() throws T {}
    void a() throws ClassNotFoundException {
	    new<ClassNotFoundException> A();
    }
}

javac error message:
A.java:4: unreported exception T; must be caught or declared to be thrown
	    new<ClassNotFoundException> A();
            ^
1 error
Comment 1 Maxime Daniel CLA 2008-05-30 07:00:05 EDT 
We believe that this is a javac bug (could not find a matching one though), especially since the following test case, added as GenericTypeTest#1149a, passes:
public class A {
    <T extends Throwable> void foo() throws T {}
    void a() throws ClassNotFoundException { 
	   new A().<ClassNotFoundException>foo();
    }
}

(the difference here being that a regular method is involved instead of a constructor).

Closing as javac bug.
