I've got a question about the Java code that writes CTF traces.<br>
Would this design provide a single trace with Java events and OS events in the same trace?<br>
Here is an example:<br>
<br>
Consider an all-Java program that sends an XML requests request over HTTP.<br>
Would like the trace detail to show Java method activity as well as OS activity that opens/closes the socket.<br>
<br>
This could be very helpful for unveiling the details of how Java code consumes hardware resources.<br>
<br>
Thanks,<br>

The way things look right now, I will have bandwidth for it in another month, so middle to end of May. Perhaps sooner if all the stars align.<br>
