Trying to get thread dump kills the java process

[pdesh]

Hi,

When I use Adaptj StackTrace to get a thread dump of a java process that is stuck the java process dies and I get an error message "javaw.exe has encountered a problem and needs to close. We are sorry for the inconvenience. Please tell Microsoft about this problem. ...". This problem is happening for all java processes.

On Adaptj StackTrace windows I see a "Please Wait..." dialog and I have to cancel out from there.

It is a Windows XP machine and I have JDK 1.5.0_14 installed. I am running Adaptj StackTrace from web.

Any suggestions on what can be causing this behavior? I have used StackTrace before and it use to work fine.

Thanks.

There are two things you can try:
1. Try to get thread dump when your process is working fine. If you can do this use the "Keep remote thread running" option (Edit->Preferences->Thread dump). It creates a thread in your target process waiting on an event. Without this option StackTrace will have to attach and do a lot of additional work in order to trigger a thread dump.
Get one dump with this option enabled before your process hangs and try to get one when you see the problem.

2. Install Microsoft DebugView from http://technet.microsoft.com/en-us/sysi ... 96647.aspx
Make sure the Debug StackTrace check box is selected under the Tools menu of StackTrace. Try to get a thread dump and send the output you see in DebugView to support@adaptj.com (or post it here).

I am seeing this problem for all java processes (even non-stuck ones). When I try to get a thread dump the java process dies. I enabled the StackTrace debug and installed DebugView.

Only output in DebugView is:

[4984] STACKTRACE: Begin inject.
[4984] STACKTRACE: The system cannot find the file specified.
[4984] STACKTRACE: C:\DOCUME~1\pdeshmuk\LOCALS~1\Temp\.aj2.tmp

When I click on Process -> Thread Dump the first line shows up in DebugView and then the java process crashes. The last two lines show up when I click on 'Cancel' in the 'Please Wait...' popup.

You may also need to run both StackTrace and DebugView as an Administrator in order to get access to all the log entries?

Do you see the same issue on a different system?

It looks like StackTrace cannot attach to your process. You should see log entries from both processes (StackTrace and the target) in DebugView.
