Thanks, Kamal, that's really good information!  This probably deserves a
bug in our JIRA issue tracker so that we can determine what we need to do
to be compatible across Java versions.  I suspect that, if it doesn't work
in 1.8.0_201, it also will not work in JDK11 or anything after that, so we
definitely need to address it.

Probably so - it depends on what Linux distribution you are running, but
you should be able to go back and install a specific version of the OpenJDK
package and get the one that works.

Interesting.  Seems this isn't the only project to encounter that:

https://issues.opennms.org/browse/NMS-9763

Nothing relevant has changed in Guacamole since I tested it when developing
it, so I wonder if the Java version has an impact or changed something.
Looks like there are some work-arounds for it, we might have to implement
one of those.
