public class JspC
extends Object

Simply call org.apache.jasper.JspC, then exit. As of Tomcat 8.5.33, forking their JspC won't complete, because the JspC compilation is now threaded and the thread pool workers aren't daemons. Will fixed in a 8.5.35, but we don't know what version distros may have. Additionally, if the system property build.reproducible is "true", attempts to generate a reproducible build by compiling the jsps in order, for a consistent web.xml file. https://tomcat.apache.org/tomcat-8.5-doc/changelog.html https://bz.apache.org/bugzilla/show_bug.cgi?id=53492 http://trac.i2p2.i2p/ticket/2307 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=908884 https://bz.apache.org/bugzilla/show_bug.cgi?id=62674 We could set fork=false in build.xml, but then the paths are all wrong.
