Subject [jira] Commented: (HARMONY-5033) [drlvm][jvmti][x86_64] FieldModificationEvent should support compressed references on x86_64
Date Sun, 28 Oct 2007 23:34:51 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-5033?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12538371
] 

Ilya Berezhniuk commented on HARMONY-5033:
------------------------------------------

Looks like the problem actually is not in compressed references.
When JET invokes rt_helper_ti_field_modification stub on x86_64, it passes 5th parameter (p_new_value
in jvmti_field_modification_callback) incorrectly.

I've filed HARMONY-5035 for this issue.

> In the jvmti_field_modification_callback argument p_new_value contains an uncompressed
reference from JIT stack. It has to be compressed in compressed mode to create an argument
for JVMTI callback. The following 2 tests crash currently:
> org.apache.harmony.jpda.tests.jdwp.Events.FieldModification002Test
> org.apache.harmony.jpda.tests.jdwp.Events.FieldModificationTest
