run GCViewer using Oracle Java build 1.8.0_251-b08

Hi GCViewer has an automatic file format detection, which sometimes results in using an inapropriate parser for the log file at hand. The error message provided unfortunately does not include enough information for me to help. Which version of GCViewer are you using? Could you please attach a sample of the logfile you are trying to parse? The beginning of the file is the most important part, because that is, where GCViewer tries to decide on the parser to use. Best regards Jörg
