We're using the OSG Jasper based plugin 2.8.3. The program dies in the readImage function with the filename string argument. It references a null pointer returned from the jasper jas_image_decode function that can be returned if it found an error. It looks like there is some global data in jasper setup during the jas_init that the decode routine uses. The jas_init and jas_image_clearfmts is called each time a file is read and in some other spots in the the ReaderWriterJP2 file so I'm guessing concurrent call's can mess up the config data from the other. We're trying out a fix that will just do the init once in the ReaderWriter constructor and return an error on the null pointer. Thanks, Matt
