Subject [jira] Commented: (HARMONY-2528) [drlvm] VM crashes instead of throwing AbstractMethodError
Date Wed, 27 Dec 2006 16:47:24 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-2528?page=comments#action_12461036 ] 
            
Alexei Fedotov commented on HARMONY-2528:
-----------------------------------------

Gregory,

I will split my patch into two patches. One will target code inspection notes, and it will
be orthogonal to Pavel's patch. I will file a new JIRA issue for that patch. The rest of my
patch (the actual fix) will be the following code in compile_jit_a_method stub - only it will
compete with Pavel's patch.

+    tmn_suspend_enable();
+    if (method->is_abstract()) {
+        compile_raise_exception("java/lang/AbstractMethodError", "Cannot compile", method);
+        tmn_suspend_disable();
+        return NULL;
+    }
