I have enable tracing and logging and show console enabled but the program I am using is crashing Java in a matter of minutes, is there anyway I can save the log directly to a file so when it crashes I can see what the last error was that was causing this? Also I have no access to the source code of this program.

Please share the command line used to start the app. – LMC May 02 '19 at 02:57

@LuisMuñoz javaws name.jnlp it launches with the console so I can read the logs but when it crashes the log disappears with it so I miss the last few errors or hints as to what is happening. – CodeCamper May 02 '19 at 03:06

`javaws name.jnlp > app.log 2&>1` should work assuming your OS is Linux. – LMC May 02 '19 at 03:17

@LuisMuñoz sorry should have specified, crash is occurring on Windows 10 – CodeCamper May 02 '19 at 03:20

I tried "javaws name.jnlp -XX:ErrorFile=c:\filename%p.log" and I am not getting any output to my C drive... the program crashes pretty often. – CodeCamper May 02 '19 at 03:17
