Both HEAD and Branch_JBossCache_1_4_0. Releases will continue to go out from both branches. JBC 2.x (HEAD) is API incompatible with 1.x, so there is no reason to test serialVersionUID compatibility with 1.x, other than for our own curiousity about what changed. So maybe we'll ignore the test on HEAD for the first 2.0.0 release. But for subsequent 2.x releases we'll need the test in HEAD.
