Could not reproduce, occurred in multithreaded application with ServerSocket and snaq.util.DBPool database connection pool to MySQL database. The database connection was open at the time of the crash and the ServerSocket was listening without any clients up to this point according to the logfile (limited using only System.out, no logging facility). The application would have been waiting in the ServerSocket.accept() function. It is possible a client connect caused this issue, in which case a ClientSocket would have been created and started listening using the InputStream.read() function. Further system information:
