This is a good idea to improve the doc. I created https://issues.apache.org/jira/browse/DAFFODIL-2485 issue so this gets tracked. ________________________________ From: Attila Horvath <attila.j.horv...@gmail.com> Sent: Monday, March 15, 2021 7:06 AM To: users@daffodil.apache.org <users@daffodil.apache.org> Subject: Re: Exception in thread "main" java.lang.StackOverflowError
Steve S. Did as you'd suggested - works as advertised. Thank you. I'd like to find/have full documentation of 'JAVA_OPTS' for future reference and use so I don't have to bother user community unnecessarily. I've looked at: * https://daffodil.apache.org/cli/ * https://cwiki.apache.org/confluence/display/DAFFODIL/Java+Setup+and+Notes Above links don't appear to list all JAVA_OPTS. Where can I get description/specifications of all relevant Daffodil options as they relate to JAVA?
