GCJ seems to incorrectly implement the following section of the Java
Language Specification:
15.9.5.1 Anonymous Constructors
http://java.sun.com/docs/books/jls/second_edition/html/expressions.doc.html#253002
"In all cases, the throws clause of an anonymous constructor must
list all the checked exceptions thrown by the explicit superclass
constructor invocation statement contained within the anonymous
constructor, and all checked exceptions thrown by any instance
initializers or instance variable initializers of the anonymous
class."
Note that the offending file Test.java compiles fine with Sun's javac.
Here's what I get with GCJ:
$ cat Test.java
import java.io.IOException;
public class Test {
public Test() throws IOException {
throw new IOException("could be any checked exception");
}
public void doStuff() {}
public void blowUp() throws Exception {
new Test() {}.doStuff();
}
}
$ gcj -v -save-temps -C Test.java
