Don,
Looking a the logs, I see some stackoverflow errors. I don’t have the
build.xml handy, but Terry N. suggested using <jvmarg> or <jvmargs> to set
the stack space of a java program. I use value=“-Xss1g” for 1GB stack
space in x3dschema/build.xml. If you have enough system resources
available, that might get you through some sticky points. That’s pretty
much the maximum value. This got me past some stack overflows in Core Java
(pattern matching) and HAnim validation.
My build.xml is here:
https://github.com/coderextreme/x3dschema/blob/main/build.xml
Please thank Terry again for solving this for me!
John
