#1 problem - java.lang.String.substring(Unknown Source)

[theARE]

I'm getting the following error when the mail clint is
trying to authenticate with localhost:

java.lang.StringIndexOutOfBoundsException: String index
out of range: -3
at java.lang.String.substring(Unknown Source)
at java.lang.String.substring(Unknown Source)

netpop.WebmailReader.login(WebmailReader.java:85)
at
netpop.Pop3RequestHandler.authorization(Pop3RequestHandler.java:80)
at
netpop.Pop3RequestHandler.run(Pop3RequestHandler.java:40)

this is with java version "1.4.2_05". Tested with
thunderbird and kmail.

Also tested the linux binary and the jar file - same
result.

Any ideas how to correct the problem?

Thanks
