Difference between Groovy 1.6 and 1.8

Question

We have recently upgraded an application in which we have our own embedded Groovy code to trigger certain things. Previously the application had the Groovy 1.6 library and since upgrading now uses the 1.8 library. However this is where we run into problems, certain pieces of code now do not run and they generally have the error:

    System exception occurred: class=class java.lang.ClassNotFoundException

Are there fundamental differences in the code I should be looking for? Or anywhere that there is a list of differences between the 2 libraries.

Thanks in Advance

There's a huge difference between (org.codehaus.) Groovy 1.6 and 1.8. I remember when I upgraded from 1.6 to 1.7, and again from 1.7 to 1.8, and neither were pleasant activities, involving lots of little code changes to get things working again. So it's likely you need to change your embedded Groovy code to make it work.
