[x3d-public] X3DJSAIL update: improved output when exporting ClassicVRML/VRML97 models

Sat Jul 6 17:48:45 PDT 2024

Here’s a variation for setting the stack space for javac:

<javac
includes="RunSaxon.java,X3DRoots.java,Validate.java,ValidateXML.java,X3DJSONLD.java,JinLOA4.java,Jin.java,Match.java"
srcdir="." destdir="." classpath="${classpath}" includeantruntime="false"
fork="${fork}"> <compilerarg value="-proc:full"/> <compilerarg
value="-J-Xss1g"/> <compilerarg value="-J-Xmx4g"/> </javac>

Enjoy!

It’s in my build.xml as well!
