HTTP 500 server exception error

[amergerm35]

I realize there was a thread that had this subject, but it's out of date and not the same exception.

We have a server that started returning an HTTP 500 error. The lead programmer is out for extended leave, so they wanted me to investigate.

When I traced it back, this is the message that was stored:
type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

java.lang.StringIndexOutOfBoundsException: String index out of range: -3

This is obvious. There is no character at position -3 in a String. You need to go through the stack trace to find out where in your code, not in Java or 3rd party library code this occurs. Then look at the line in that class and find out why it is getting an index of -3.

Thanks for the reply. I'll ask our secondary programmer to start there.
