[jboss-dev] Snapshots on trunk?

How this snapshot thing happens? I have created a branch for my work on HornetQ's integration. I haven't changed anything, however time to time things will stop working and I have to change the classpath on the testsuite: compile-annotated-classes-50: [javac] Compiling 255 source files to /work/as6/jboss-as-parent/testsuite/output/classes BUILD FAILED /work/as6/jboss-as-parent/testsuite/build.xml:723: Reference javax.faces:jsf-api:jar not found. that means... once I make a branch, I can't guarantee it will build tomorrow because of the snapshot changes and dependencies? I thought this issue was solved
