[jira] Created: (HARMONY-4515) [drlvm] ClassCastException is thrown
with low detail
[drlvm] ClassCastException is thrown with low detail
----------------------------------------------------
Key: HARMONY-4515
URL: https://issues.apache.org/jira/browse/HARMONY-4515
Project: Harmony
Issue Type: Bug
Components: DRLVM
Reporter: Vasily Zakharov
DRLVM, when throws ClassCastException, provides no detail about what were the class being cast and the target for the cast. This makes localizing problems in applications more difficult.
RI provides information only on the class being cast, and IBM VME provides information on both.
This situation is not certainly a bug, it may be considered an Improvement or Non-bug difference from RI. However I think DRLVM should better follow the IBM VME behavior, or, at least, RI behavior, to improve its usability.
Test to reproduce the problem:
public class Test {
public static void main(String[] args) {
try {
Class c = (Class) (Object) "test";
} catch (Throwable e) {
e.printStackTrace();
}
}
}
Output on RI:
java.lang.ClassCastException: java.lang.String
at Test.main(Test.java:4)
Harmony/IBM VME:
java.lang.ClassCastException: java.lang.String incompatible with java.lang.Class
at Test.main(Test.java:4)
Harmony/DRLVM:
java.lang.ClassCastException
at Test.main(Test.java:4)

[jira] Updated: (HARMONY-4515) [drlvm][jit] ClassCastException is
thrown with low detail
Posted by "Gregory Shimansky (JIRA)" <ji...@apache.org>.

Gregory Shimansky updated HARMONY-4515:
---------------------------------------
Priority: Minor (was: Major)
Summary: [drlvm][jit] ClassCastException is thrown with low detail (was: [drlvm][classloader] ClassCastException is thrown with low detail)
Patch for class loader and interpreter is applied at 562267. However when running in JIT mode there is still no details when CCE is thrown. So I am reassigning this bug to JIT to complete the work.

Attachment: H4515.patch
This patch makes DRLVM compatible with Sun in interpreter and Jet lazy mode. Opt mode should be fixed further.

------------------------------------------
Gregory, the problem seems to be resolved both in Intepreter and JIT mode - it works fine for me on both Windows and Linux.
Could you please double check it in your environment to make sure the problem exists?
Thank you!
