LinkageError from JSP pages

[Brian Gardner]

I'm trying to use DCEVM in my project and have had some success.  I'm still needing to perform a ton of restarts because of these LinkageError's coming from my JSP pages.  

HOTSWAP AGENT: 15:44:55.520 INFO (org.hotswap.agent.plugin.tomcat.TomcatPlugin) - Tomcat plugin initialized - Tomcat version '8.5.45.0'

HOTSWAP AGENT: 15:45:04.456 INFO (org.hotswap.agent.config.PluginRegistry) - Plugin 'org.hotswap.agent.plugin.tomcat.TomcatPlugin' initialized in ClassLoader 'ParallelWebappClassLoader

It looks like the TomcatPlugin in initializing the ParallelWebappClassLoader correctly.  Any ideas?
