ReplaceText Infinite loop?
Hi
I'm extracting text from the following sentence using a regex:
dummy$GPRMC,123519,A,4807.038,N,01131.000,E,022.4,084.4,230394,003.1,W*6A
The placing the content into a json (using replacetext).
I think ReplaceText is in an infinite loop due to the $ sign in my first field.
How should I handle these cases? Isn't NiFi supposed to escape any
character in an attribute?
Thanks!

Stephane
This definitely needs to be looked at. Would you mind raising JIRA for it?
Thanks

In the first ReplaceText, replace a,b,c,d by a$a,b,c,d (it simulates data that may or may not contain a $ sign)
Launch the flow, you'll see the errors / warning / infinite loop

Launch the flow, you'll see the errors / warning / infinite loop
