Hi Erik, Typically, you would have one trace for your kernel events, and a separate one from the Java parser.
In TMF, you can open multiple traces at the same time in what we call experiments. This allows you to see events coming from different traces in the same list. With regards to trace synchronization, an initial synchronization infrastructure was submitted at https://git.eclipse.org/r/#/c/10869/ . If you have events in both your kernel and your Java trace that can be used to synchronize them together, it could be hooked into this infrastructure. We are hoping to merge it shortly after the Kepler release.
