I’ve had a weird issue when testing Lucee 6.2.1.122 with functionality that uses the createDynamicProxy() function. I cannot recreate the problem consistently. Sometimes after a fresh install of Lucee 6 (no installer, using the release JAR w/Tomcat 11), trying to use the createDynamicProxy() I will see the following exception:
lucee.runtime.net.rpc.RPCException: No Webservice Engine is installed! Check out the Extension Store in the Lucee Administrator for "Webservices".

If I install the Axis Webservice extension, the error goes away. I can then delete the extension, restart Tomcat and it will continue to work.
Also, sometimes after a fresh install (folders, wiped, complete re-download and setup), the error never happens. Seems fairly random. I haven’t dug into the code on why it thinks it needs the Webservice extension. I can’t see why it would need it.
Any ideas on why this is happening? Even though I can’t reliable recreate the bug, should I file a bug report?
