Hello,
I shared this issue on the user ML a few weeks ago.
If it's ok I'll start working on a fix for this.
Ticket is here https://issues.apache.org/jira/browse/TEXT-223.
Happy holidays.

Subject: [text] StringSubstitutor checks for cycles even if substitution in
variables is disabled
To: <u...@commons.apache.org>
Hello,
I'm trying to use StringSubstitutor. Substitution in variables (recursive
substitution) is disabled.
When I run with a variable cycle, I don't expect an infinite loop because
recursive substitution is disabled. But I still get the exception:
java.lang.IllegalStateException: Infinite loop in property interpolation of
my template ${cycle}: cycle.
See example code below.
import java.util.Map;
import org.apache.commons.text.StringSubstitutor;
public class TestCycles {
public static void main(String[] args) {
final Map<String, Object> cycleMap = Map.of("cycle", "${cycle}");
final StringSubstitutor sub = new StringSubstitutor(cycleMap)
.setEnableSubstitutionInVariables(false);
String res = sub.replace("my template ${cycle}");
}
}
Is this the expected behavior, or do you think this should be fixed?
Thanks.
