I am having problems with Opal.-5.8.0 firstly I get the message below, then
I can't list or use the methods in the default profile image.

opal-1   | Starting Opal...
opal-1   | No org.slf4j.impl.StaticLoggerBinder found in ClassPath, trying with log4j2...
opal-1   | WARNING: A restricted method in java.lang.foreign.Linker has been called
opal-1   | WARNING: java.lang.foreign.Linker::downcallHandle has been called by the unnamed module
opal-1   | WARNING: Use --enable-native-access=ALL-UNNAMED to avoid a warning for this module

Is the lack of "-enable-native-access=ALL-UNNAMED" root cause, or do you think it is not relevant?

Hi Stuart, 

I guess you are talking about Opal 5.4.0

How do you run it?
Which client app are you using? gui or R or ?

Regards
Yannick

Hi Yannick,
     Sorry that should, naturally be 5.4.0, I was in a rush.

I have not been able to repeat the problem. I suspect I was trying to connect during that first "Starting" phase.
If I wait for the "restart" it properly connests.

R - 4.4.1
dsBaseClient - 6.3.5.9000
DSI - 1.8.0
DSOpal - 1.5.0
opalr - 3.5.2

Yes, it starts twice, once for executing upgrade tasks if any, and a second time for real.

Cheers 
Yannick
