Use of the pipe separator in a java start argument

We have been running WebLogic Server Version: 12.2.1.1.0 with jdk1.8-u101 and have a server start argument, which contains multiple entries separated by the pipe (|) character. The syntax being:

-Dhttps.nonProxyHosts=localhost|*.domain1|*.domain2 

We are upgrading to WebLogic Server Version: 12.2.1.4.0 with jdk1.8.0_202 and if we use the same syntax the managed server fails to start.

Should we be using a different syntax?

We have not yet been able to locate any helpful articles or information regarding this potential syntax change.

Any help would be much appreciated.

Thanks
