Send ctrl-break to java process on 64-bit Windows ala sendsignal on 32-bit

I frequently use the sendsignal tool for WebSphere Application Server processes (server, launchClient, wsadmin, etc.) in order to generate heap dumps. However, sendsignal doesn't work on 64-bit machines. Does anyone know of an alternative for sending the ctrl-break to a remote process?

Update: Bengt points out that this is basically the same as the following question. So, I guess my question is: has anyone found a way around this limitation in the past two years?

Can I send a ctrl-C (SIGINT) to an application on Windows?
