Hello, thanks for your answers.
I repeated my tests and also got problems with "-Xmx4g" ... The problem only occurred when I used the JBIG2-library with levigo and had several threads. Maybe there is a threading problem: It seems that levigo is not thread-safe. When I used it with 5 threads, all five threads were blocked after about one hour. All threads were locked in HashMap.getEntry() (after calling a class of levigo).
