Ralph Goers commented on LOG4J2-3306:
-------------------------------------
Yes, StrSubstitutor and OptionConverter.substVars have very different
behaviors. I reverted the code and fixed the original problem.
We have done 4 releases in the last month, which gets very confusing for users.
We don't follow a normal release schedule but typically release when we feel
the release has sufficient content. It is certainly possible we might do a
release later in the month but I can't guarantee it.
> OptionConverter can get a StackOverflowError.

> Prior to 2.17.1 OptionConverter could get a StackOverflowError by returning
> the same lookup string. In 2.17.1 it was changed to use StrSubstitutor which
> fixed the problem but introduced a different way a StackOverflowError could
> occur.
