[jira] Created: (HARMONY-4068) Jetty scenario fails on DRLVM with
access violation exception
Jetty scenario fails on DRLVM with access violation exception
-------------------------------------------------------------
Key: HARMONY-4068
URL: https://issues.apache.org/jira/browse/HARMONY-4068
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: Windows XP, ia32
Reporter: Ivaschenko, Aleksei V
Hello,
the Jetty scenario intermittently fails (chance to fail is up to 70%) on DRLVM with access violation exception in VM which runs the Jetty server. Exception is thrown from gc_gen module (gc_for_class.h file, line 198):
gc_gen.dll!vtable_get_gcvt_raw(Partial_Reveal_VTable * vt=0x00021b08) Line 198

[jira] Updated: (HARMONY-4068) [drlvm]Jetty scenario fails on DRLVM
with access violation exception

Xiao-Feng Li updated HARMONY-4068:
----------------------------------
Assignee: (was: Xiao-Feng Li)
Summary: [drlvm]Jetty scenario fails on DRLVM with access violation exception (was: [drlvm][gc_gen] Jetty scenario fails on DRLVM with access violation exception)
Investigation shows this is not a GC ｂｕｇ．Ｂｕｔ I am not sure which component causes this bug.
Although the break sometimes happens in GC, it is caused by an incorrect dead object before entering GC, and the object became incorrect between two collections (instead of inside a collection). It's just exposed by GC.
Then why GCv4.1 doesn't have the break? That's because GCv4.1 uses different algorithm that doesn't traverse the heap linearly for live objects. GCv5 goes through the heap one byte by another to identify live objects - it checks next object from current object's end, and next next object from next object's end. This has no problem in cases of the next object is alive or dead, since its contents are not destroyed, thus we can always compute its size from its vtable field. However, if the vtable is destroyed, GCv5 will break. But this dead broken object is destroyed by the mutator already. GCv4.1 doesn't work this way. It discovers live objects with markbit table, so it never needs to touch dead object.
Specifically, the destroyed object header vt field is filled with a native pointer pointing to a sequence of ASCIIs something like "The socket is marked as nonblocking ...". This ASCII string is outside of GC heap. In my understanding, it is impossible for GC to know a native pointer, and a native ASCII string. GC verifier can always catch this wrong object before starting a collection.
This dead object looks like a long array [J field of Java/Net/SocketException object. This long array is dead when GC happens, and its vt field is filled with a native pointer.
Moreover, the object vt header field is written by <init> method of "org/apache/harmony/luni/util/ErrorCodeException", which is a created object by API native function throwJavaNetSocketException, which in turn is called in Java_org_apache_harmony_luni_platform_OSNetworkSystem_writeSocketDirectImpl.

Thanks Tim,
the patch applied as expected and looks like it resolves the issue completely - Jetty scenario passed in 100 of 100 runs.

[jira] Reopened: (HARMONY-4068) [classlib][luni] Jetty scenario
fails on DRLVM with access violation exception
Posted by "Ivaschenko, Aleksei V (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-4068?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ivaschenko, Aleksei V reopened HARMONY-4068:
--------------------------------------------
Estimated Complexity: (was: Unknown)
Hello Tim,
I've found that the issue is not resolved completely. It just started to reproduce a bit rarely. The reason is that wrong constructor is used for creating java.net.SocketException - looks like a typo. I've created patch that fixes this typo.

[jira] Updated: (HARMONY-4068) [classlib][luni] Jetty scenario

Ivaschenko, Aleksei V updated HARMONY-4068:
-------------------------------------------
Component/s: (was: DRLVM)
Classlib
Summary: [classlib][luni] Jetty scenario fails on DRLVM with access violation exception (was: [drlvm]Jetty scenario fails on DRLVM with access violation exception)
Xiao Feng, thanks for the investigation!
I've found that the java.net.SocketException you mentioned is created incorrectly in classlib's luni module (in case of "The socket is marked as nonblocking ..." reason of exception only). This exception is created by JNI function NewObject() using char* variable instead of jstring one to pass error message to SocketException constructor.
