GenericDialog limited to 25 sliders

Hi,

I ran into a confusing bug that ImageJ crashes with an outofbounds exceptions when using >= 25 sliders:

Exception in thread "Thread-3" java.lang.ArrayIndexOutOfBoundsException: 25
at ij.gui.GenericDialog.addSlider(GenericDialog.java:646)

This behaviour is wanted since there is a "public static final int MAX_SLIDERS = 25;”, which defines the array size.

Would it be ok to remove this limitation? It seems rather random and from my point of view it seems to make not much sense. But even if, it should not crash but throw a defined exception.

Thanks a lot,
Stephan

This bug is fixed in the latest ImageJ daily build (1.51m29).

When there ever was a movie from Disney:
The Pirates of beyond the 25 sliders...

Wayne would be "Captain White Hair of the Bug Bounty".. a fast sailing
ship known to each guy around these waters and java tides..

Ahoi there and all the best to everyone..
