New tomcats 9.0.34 seems to fail when uploading new war when theres a
context in server.xml pointing to the particular exploded war. Says 'The
main resource set specified is not valid.' It's like hot deploy is deleting
the old webapp and restarting tomcat?
<Context path="/" debug="0" privileged="true"
docBase="/home/some/path/tomcat/webapps/webappName">
</Context>
To work around this one has to comment out the above context, start tomcat
so the war will deploy, uncomment and then restart tomcat again.
