Hi Tom, try vmconnect instead of nla for security. See https://issues.apache.org/jira/browse/GUACAMOLE-952.

I will be happy with a working solution ;-) For the last week I have been fruitlessly trying to compile the git version of guacamole-client using maven. With openjdk-13 or openjdk-14 installed I receive this error when running nvm -X package error: Source option 6 is no longer supported. Use 7 or later. With openjdk-11 installed I receive this error Exit code: 1 - javadoc: error - The code being documented uses modules but the packages defined in http://docs.oracle.com/javase/6/docs/api/ are in the unnamed module. which supposedly is fixed in 11.0.8 and higher; https://bugs.openjdk.java.net/browse/JDK-8212233 which will release in July. Yeah, if you have an option to use JDK8, I would use that, instead. 11 *should* work, but there may be a Maven issue that blocks that. 8 works consistently. -Nick
