You get a 404 error related to GWT

You get the following error after upgrading to v4.1 of SynaMan.

Why is this happening

SynaMan runs on top of Java. You run into this error if the version of Java is very old. To see the version of java, type http://yourHostName/app?operation=sinfo and refer to the java.runtime.version. A value less than 1.8 is considered old.
