java exception during Resave Dataset

[pawlowska]

I have a 2-channel dataset stitched with Bigstitcher and saved as xml/hdf5. I need to extract 1 channel for further processing, so I tried Resave Dataset -> As TIFF... . I get asked if I really want only one 'view' and if I agree to saving current state of XML. No files get created and a java exception happens.

I subsequently tried Resave Dataset -> HDF5 for only 1 channel and this doesn't crash.

Console output:
