Answer "Yes" to instruct JavaTest to start a separate process every time a new schema is compiled/generated or a new test is executed. In this case, the schema compiler, the schema generator and all tests will work in the so-called "multiJVM" mode.

Answer "No" to compile/generate all schemas and execute all tests in a single process, the Agent's JVM. In this case, the schema compiler, the schema generator and all tests will work in the so-called "singleJVM" mode.

For more information about test run modes, refer to the JavaTest User's Guide and to the JAXB TCK User's Guide.
