Java 1.5 is not supported

[GoogleCodeExporter]

What steps will reproduce the problem?
1. include library to any Java 1.5 project (2.5.1 lib version)
2. compile and make any valid request to the notification responder servlet
3. you will get an error methods doesn't exist exception (String.isEmpty())

Is this correct, that Java 1.5 is not supported because of 1 using of 1 method 
in the code?

library version: 2.5.1 under Java 1.5+

Thanx for understanding

For what it's worth. I'm using the 2.5.1 lib in a java 1.6 project and it works 
fine for me.
