seeing blocking threads in debugger? [message #183908]

I'm using eclipse 2.1.2 to debug an application. I can see the threads
in the thread view, does it indicate in any way which threads are
blocking on something? Or is there a way to find this out?

thanks
alex

Use the "Threads & Monitors" view - available from the "Window > Show View".
Pause the threads you want to know about (or the entire VM), and info will
appear in the view. You can toggle between threads, monitors, and deadlock
(cycle detection).

I've activated this view, and it contains the text "The currently
selected VM does not support the retrieval of monitor information".
I'm using jdk1.4.1_05, and the java compliance version in eclipse is set
to 1.4.
Is there some setting I'm missing that will allow monitors to be viewed?
cheers,
alex

See http://dev.eclipse.org/newslists/news.eclipse.tools/msg48270 .html for
full details.
1.4.1 does not support this functionality. You will need to run your program
on 1.4.2 or 1.3.1 and use the -classic VM argument.
