I'm trying to compile a java project by a development version of aspectbench
compiler with tracematch extension (-ext abc.ja.tm) checked out from the svn
repository (http://abc.comlab.ox.ac.uk/products/trunk/abc-full) on September 2,
2009. But I can't compile the project when I define any piece of around advice
by tracemacth and receive the following error message:

Though it is not a problem to compile my small sample code with tracematch's
around advice, my target java code (about 2,000 lines of code) with any piece of
tracematch around advice causes the above compile error.
The error is caused by defining a simple tracematch's around advice like this:
    void tracematch() {
        sym callEvent around :
            call(void TextEditor.changeBlock());
        callEvent {
In addition, It is not a problem that I define after/before advice by tracematch
and 'normal'(pure AspectJ's) around advice.

In fact, I tried to compile my java code by the latest stable version of abc
(version 1.3.0), but I got a compile error about advice precedence. This bug is
fixed by the current development version of abc, isn't it?
