Connect Tunnel and OnDemand Tunnel Clients Do Not Launch on Mac OS X Systems or Cannot Make a Connection

Problem Definition:

When the wrong Java environment is used on a Mac OS X system, the following behavior will be seen:

Neither Connect Tunnel nor OnDemand Tunnel will launch and no explanation is given.
Connect Tunnel or OnDemand Tunnel may launch, but they will not be able to make a connection to the appliance.

Resolution or Workaround:

In order to resolve this issue, a Mac OS X system should use the 32-bit J2SE 5.0 Java application environment. To configure, follow these steps:

Open Applications > Utilities > Java in the Mac OS X Finder.
Open the Java Preferences application.
Under Java application versions make sure that the 32-bit version of J2SE 5.0 is at the top of the list. Java SE 6 is not yet fully supported, and J2SE 1.4.2 will not work with the tunnel clients. When properly configured, the Java Preferences application will look like this:
Close the Java Preferences application and then restart the tunnel client.

Note: Java + CT (12.4.1) has native Apple Silicon support, Apple Silicon Java can be found here https://www.azul.com/downloads/?package=jdk”
