org.springframework.beans.FatalBeanException type mismatch between read and write methods

Question

I have a web application written using Grails 2.2.4. To this point we have been compiling and running it using the IBM 1.6 JDK on AIX because our AIX version did not support 1.7 or higher.

We recently updated our AIX version so we can now support 1.7 and 1.8. We need to do make use of 1.7 at minimum with our Grails 2.2.4 application so that we can use TLS 1.2.

When we try to use the IBM 1.7 JDK we get errors in some of our unit tests like:

It happens in 37 of 1272 tests and only when tested under the IBM 1.7 SDK. When run using Oracle or OpenJDK the tests run with no failures.

Does anyone know how to get around this?

On deployment and startup (using Tomcat ) it shows up a little differently.
