Investigate Observed Exceptions #3

Open stephanheinemann opened 7 years ago

stephanheinemann commented 7 years ago

Several exceptions including NPE and CME have been observed during initial testing. Investigate and fix these problems. In general, all concurrent threads and their resources should be examined carefully to avoid any race conditions.

The following exception was triggered while creating a new planning grid environment with a previous environment and plan present in order to modify the grid layout and obtain a different trajectory.

The CMEs are mainly related to passing only unmodifiable collections to the GUI thread. These are views on the original scenario collection which are being modified by the core logic. Hence, collections passed to the GUI thread need to be immutable instead: unmodifiable clones of the original collection.

This one appears to happen sometimes when trajectories are redrawn although the drawing should always happen from the EDT.

This one was observed during AD* planning. Possibly an issue during repair which introduces null waypoints into the open queue for expansion?
