This was required by the Eclipse team as one precondition for the next
release.

There were some problems in file handling: One file in was not deleted
in case an exception was thrown during the test. Another case was a
JarFile which was not closed before deletion, which might work on Linux,
but not on Windows where the open file is still locked after usage.

These changes are both (a) a performance optimization, and (b) an
improvement on the binding across || rules that we implemented in
1.2.1.
Instead of saying the the first binding in a left-to-right traversal of the
pointcuts DNF is the one that you get (too much to ask users to do DNF
rewriting in their heads), this version implements the rule that every
|| branch in the DNF must bind all formals, and if two || branches can have
any join points in common (can match join points of the same kind), then
both must bind all formals identically.

So it allows things like execution(* *(..)) && args(x) || call(* *(..)) && this(x)
which previously we used to forbid.

But primarily it turned out to be a performance optimization.
