Camel Debugger broken when an Exhange has no timestamp provided

Using CBRroute project,
1. Set unconditional breakpoints on all nodes that support them
2. Debug As Local Camel Context with or without tests.
3. Switch to Debug perspective
The debugger appears to be running, but Debug view freezes before displaying the first breakpoint in the routing context and Variables view remains empty, but Console View's output shows the debugger continuing to dump traces. Trying step over does nothing to update Debug View or populate Variables View.
