Description
Open Boats. Add axes (size 2 each) in this order (polarization, z, t). Each time an axis is added an exception is dumped to the console. The bad array index always equals the last one in the changed dataset which may be one beyond the view's index. The view may have not yet been updated and thus cannot find a given dimension.
Caused by: java.lang.ArrayIndexOutOfBoundsException: 4

I think earlier I had tested with rev 4107 or later. Since no code changes since then seem relevant this does seem like a race condition.

Tested with f2539ec742ef9a8957c832faea72e3caacec11cd and still exists. Just adding a Z axis size 2 to Boats caused it.
