While a lot of things seem to have been fixed in 8u60 I just noticed new weird things with regards to the selected Items of a table. If you run the following program and do nothing (i.e. not select anything at all) I would expect that selectionChanged ist never called (since the selection does not in fact change).

However the output is:
Added: [0Doe]
Reloading
Removed:[0Doe, 1Doe, 2Doe, 3Doe, 4Doe, 5Doe, 6Doe, 7Doe, 8Doe, 9Doe, 10Doe, 11Doe, 12Doe, 13Doe, 14Doe, 15Doe, 16Doe, 17Doe, 18Doe, 19Doe, 20Doe, 21Doe, 22Doe, 23Doe, 24Doe, 25Doe, 26Doe, 27Doe, 28Doe, 29Doe, 30Doe, 31Doe, 32Doe, 33Doe, 34Doe, 35Doe, 36Doe, 37Doe, 38Doe, 39Doe, 40Doe, 41Doe, 42Doe, 43Doe, 44Doe, 45Doe, 46Doe, 47Doe, 48Doe, 49Doe]
Added: [0Doe]
