     [ http://issues.apache.org/jira/browse/HARMONY-1985?page=all ]

Eugene S. Ostrovsky updated HARMONY-1985:

    Attachment: H-1985_Fix.patch

There's a bug with event_threads array allocation in jvmti_direct.h.
Array size is less than it should be.
Proposed patch fixes this issue.

>                 URL: http://issues.apache.org/jira/browse/HARMONY-1985
>             Project: Harmony
>          Issue Type: New Feature
>          Components: DRLVM
>            Reporter: Eugene S. Ostrovsky
>         Assigned To: Gregory Shimansky
>         Attachments: H-1985-JVMTI-VMObjectAlloc-event-support.patch, H-1985_Fix.patch
> Implementation of the new profiling support feature:
> "VM Object Allocation" event.
> The proposed patch does the following:
> 1. Creates a wrapper function for gc_alloc() which will send the events to jvmti agents
right after calling gc_alloc().
> 2. Calls this wrapper in place of gc_aloc() in the following cases:
>   (i)   allocation of j.l.Class objects in class loader
>   (ii)  allocation of strings in VM
>   (iii) allocation of the clone object in Object.clone () implementation
