JavaTest generates COF files after actual test run is completed by invoking special utility:
java -cp javatest.jar com.sun.javatest.cof.Main
This provides the users with very handy possibility to generate COF files any time after the actual run is completed. But at the same time this allows to run COF generation on the host different from the original one where tests were executed. It was found that in this case JavaTest puts incorrect information about the platform in COF. This should be fixed as providing wrong information results in reporting systems that use COF (QARE).
