#334 - fix log message pattern to include parameter index

[Gozke]

This is my fix for issue #334.
I did a string search for {} and fixed the relevant occurences one by one.

Testing done

I created locally a log config to dump everything to the console and ran a few unit tests that were known to create the problematic log messages.
My src/test/resources/logging.properties file looked like this:

handlers=java.util.logging.ConsoleHandler
.level=ALL
java.util.logging.ConsoleHandler.level = ALL
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
