HDFView 3.1.0 Line Plot causes freeze

Hi,

when using HDFView 3.1.0 and try to use the line plot feature, one core goes to 100% and the rest of the program freezes. I had the same behavior for a custom compiled version and (after realizing that I could use the centOS distributable on Ubuntu as well, because it’s java) also with the official distribution.

No warnings / error logs. What might be causing this? is this a known problem?
