Log Message:
-----------
Removed test cases not applicable to Jython. Although it's not
possible to implement jump when compiled to Java bytecode, it's
possible that we can better align our trace with what is done in
CPython, so this should be revisited at some point.

+# Tracing in Jython works somewhat similarly to CPython, with the following exceptions:
+#
+# - No support for jump. Can't do that without dynamic bytecode
+#   rewriting OR at least until we support a Python bytecode
+#   interpreter
+#
+# - Some differences in how we compile, which results in different
+#   trace orders. This is of course an implementation detail. For
+#   example, we do not bother to dead-code while 0: loops because the
+#   JVM does a good job of that (and more aggressively than CPython
+#   for example, it should be to see comparable things like while
+#   False).
+#
+# - Related to this, we record f.setlineno in too many places in our
+#   code and not at all in the try, since this doesn't correspond to a
+#   bytecode on the JVM. The latter records events separately.

 # Testing the line trace facility.
