Gradle Daemon - Caused by: java.lang.Error: factory already defined

[sgoldstein527]

When using the Gradle daemon (the default), I'm unable to run Tomcat twice using the plugin. The first time it starts, there is no problem. I then run "gradle tomcatStop" followed by "gradle tomcatRun" to restart Tomcat. I get the error/stacktrace below. If I run, "gradle --stop" to stop the gradle daemon, I'm once again able to run "gradle tomcatRun" successfully.

I'm using the plugin version 2.5 and Tomcat version 9.0.22.
