7105: Unable to open graph-view if JMC is booted with JDK 8

[aptmac]

This one-liner PR addresses JMC-7105 [0], in which the GraphView is unable to open when JMC is launched with JDK 8.

The problem here is the usage of List.of() [1], which is supported in JDK 9+ [2], but not available in JDK 8 [3].

This PR simply changes List.of() to Arrays.asList() to make it JDK 8 compliant.
