Confusing Compiler ErrorMessage since 3.4.2 [message #258916]

Tue, 03 March 2009 04:43

Eclipse User

Hello,

since 3.4.2 Eclipse compiler throws error on following test case:

public class Test <T extends Comparable<String>> {

private T<String> x;
}

Error: The type T is not generic, it cannot be parameterized with
Argument<String>

Ok, i know this looks not nice and isn't necessary, but with with eclipse
3.4.1 there was no error. Anybody knows about this change ?

Failure to detect the error was a bug which seems to have been fixed
in 3.4.2.

Sun's javac (1.6.0_07) gives an error message for that class that I
would consider harder to understand:

Test.java:3: unexpected type
found : type parameter T
required: class
private T<String> x;
^
1 error

Thx for your help. I searched bugzilla, but didn't find an entry for this
one, but no problem - fixing is trivial.
