This customer was using Java version 1.7 from install of NFA 9.1.0, when they installed NFA`9.1.2 it 'comes' with Java 1.6.41. The clash of these twoversions caused this problem.

Customer uninstalled 1.6.41 to use 1.7 and all was then fine.

Solution - so make sure you do not install an older version of Java over a newer version. or uninstall the newer version first before upgrading.

For the CA NFA 9.1.2 install guide it says;

Java Runtime Engine (JRE) 1.6u41 which is included with the ISO files from CA Technical Support.
