B4J Question [B4J] Webview app has SSLException, JDK 11.0.1 B4J 8.90

[swChef]

Attached is a simple webview in a B4J app, that loads a URL, which tries to establish a SSL connection.
It fails with javax.net.ssl.SSLException: No PSK available. Unable to resume.
The log (at bottom of this post) matches the log in the JDK issue report at JDK-8213202.
I have not yet found a solution.
It occurs in debug and release mode when run from the IDE.
For whatever reason with the attached app, on occasion the exception/trace doesn't appear in the log upon the first LoadURL occurrence. It did at first.
Issue reproduces on a different PC. Both W10, one Home, one Pro.

Using B4J 8.90 and C:\Program Files\Java\jdk-11.0.1\bin\javac.exe

Waiting for debugger to connect...
Program started.

[note: in this log listing, at this point in time, I had to click on another stock/index such as the DOW at the top of the page to cause the log to 'fill', with a 'duplicate' trace below]

The following eliminates the log error/trace, but the charts still don't display, which may be a second issue.

    SetSystemProperty("deployment.security.TLSv1.2", "true")
    SetSystemProperty("https.protocols", "TLSv1.2")

TLSv1.3 gives the same result. TLSv1 and TLSv1.1 do not.
