[Pdl] java 17 compatibility

[Fee, Jeremy M]

Hello,

We received a report of errors running PDL with Java 17 when connecting to an EIDS-based hub (prod01-pdl01 or prod02-pdl01).  An example stack trace is included below.


To work around this issue in the short term, you can add an "--add-opens java.base/java.lang=ALL-UNNAMED" argument to the command line used to start PDL.  This argument should appear before "-jar":

java --add-opens java.base/java.lang=ALL-UNNAMED -jar ProductClient.jar --configFile=config.ini --receive
