/**
 * Test that the synthetic context bundle's class loader is used as the TCCL for a PAR.
 * <p/>
 * A bundle "b" in the test PAR invokes a static "run" method in a bundle "global" outside the PAR. The run method
 * attempts to load a class "AClass" of a package exported by bundle "a" in the PAR (but not imported by bundle "b")
 * using the current thread context class loader (TCCL). The TCCL should be the class loader of the synthetic context
 * bundle of the PAR and this class loader should be able to load classes from all packages exported by bundles in the
 * PAR, including "AClass".
 * <p/>
 * For the source of the PAR and "global" bundle, see test-apps/synthetic-tccl. Instructions for building are in
 * README.TXT.
