How to Use Eclipse to Debug JNI code (Java & C/C++)

While I can debug my application with the Eclipse JDT debugger for Java code and GDB for C code, I would prefer to use a single tool for all my debugging. I found several projects that enable "mixed-mode" debugging in Eclipse and include support for single stepping between Java and native code. Intel's Integrated Debugger for Java/JNI...

Is there a JVM aimed at debugging concurrent software?

I've used Concurrent Pascal, a tool which helps debug concurrent algorithms because when it runs your code, it randomizes which thread to swap to at every possible step, trying out as many paths as possible. Is there a JVM that can do this? ...

Why does ruby-debug say 'Saved frames may be incomplete'

From time-to-time I get this when a breakpoint is triggered. It looks like stack frames aren't getting saved so I can't step back through the call stack - a real pain. See below for an example --> #0 BatchProcess.add_failure_record(row_id#Fixnum, test#Struct::Test, message#String,...) at line server/processes/batch.rb:309 Warnin...

F10 isn't working properly in VS2005

When project is stopped (not in the debugging state) and you press F10, normally the debugging session starts and VS stops at the entry point (e.g. Program.Main). That always worked for me in VS2005 and works OK in VS2008. But recently that stopped working in my VS2005 - the project just runs as if I pressed F5, so I have to place a brea...

Is there a way to trace through only project source in Delphi?

I'm using Delphi 2010 and I'm wondering if there's a way to trace through code which is in the project without tracing through calls to included VCLs. For example - you put in a breakpoint and then use Shift+F7 to trace through line-by-line. Now you run into a call to some lengthy procedure in a VCL - in my case it's often a Measuremen...
