I am tearing what little hair I have left out on this.
Copilot and Grok run round in circles.
I am attempting to filter logs in a non-ui B4J app (an ABMaterial framework web app):
In DEBUG mode it compiles OK but fails with run time error:
filteredStream.InitializeNewInstance("PrintStreamWrapper", Array(originalOut, Me))
I know I'm doing something stupidly wrong but what?
Any help gratefully accepted...
EDIT: see final solution here:
