Question
Error Message : java.lang.StringIndexOutOfBoundsException: String index out of range: -1 | End User Screen Display Error.
Hi Team,
Below mentioned error message has been displayed on the end user screen.Refer to the first attachment regarding the error screenshot.
Object key:-Read/Write:true Error message:java.lang.StringIndexOutOfBoundsException: String index out of range: -1
Couldnt find anything related to the issue facing end user in the logs but found a different stack trace (String index out of range: -2) during a different time period (refer to the second attachment for the log).
1) Why and when does the following exception "StringIndexOutOfBoundsException" occurs ?
2) What is the difference between "String index out of range: -1" vs "String index out of range: -2" ?
3) Any recommendations to avoid running into the same issue ?

Can you please explain more about the use case. Are you trying to source a data set?
This exception has been observed on intermittent basis and we couldnt pin point to any specific use case.
Moreover, We dont use DSM framework or its related components (not sure how the logs error stack is all about Dnode).Looking out for answers regarding the below mentioned :
1) Why and when does the following exception "StringIndexOutOfBoundsException" occurs ?
2) What is the difference between "String index out of range: -1" vs "String index out of range: -2" ?
3) Any recommendations to avoid running into the same issue ?
PradeepPydi did you get any update on this request?
Even our application doesn't use dsm framework as of now but this exception is observed in PDC.
Hey Pydi,
Did you get resolved the above issue. Any solutions?
Thanks,
Ramesh
Nope.
No response from Pega Engineers.
Hello,
The attached stack is coming from PegaRULES-ALERTS log right. I'm surprise you not having any further details on PegaRULES logs.
Can you double check?
