Description

When attempting to build guacamole-client against JDK 11, the guacamole-auth-cas portion of the build fails with the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.3:compile (default-compile) on project guacamole-auth-cas: Compilation failure: Compilation failure: 
[ERROR] guacamole-client/extensions/guacamole-auth-cas/src/main/java/org/apache/guacamole/auth/cas/ticket/TicketValidationService.java:[31,21] error: package javax.xml.bind does not exist
[ERROR] guacamole-client/extensions/guacamole-auth-cas/src/main/java/org/apache/guacamole/auth/cas/ticket/TicketValidationService.java:[164,34] error: cannot find symbol

This is apparently because the java.xml.bind package was deprecated as a part of the JDK in version 9 and finally removed in JDK 11. It continues to exist in non-deprecated form, but now must be pulled in manually as a dependency:
