[jboss-dev] Byteman 1.2.2 release now available

[Andrew Dinn]

The 1.2.2 Byteman release is now available for download. It includes a 
small number of bug fixes as well as a few interesting additional 
features, most notably:

the problem which was causing rule injection into superclasses to fail 
intermittently (BYTEMAN-80) has been resolved. more importantly, the fix 
has avoided adding significant costs to class loading. So it is still 
possible to inject rule code through interfaces and down class 
hierarchies without seriously perturbing execution of the original 
application.

expressions in rule scripts may now employ the new operator(BYTEMAN-85) 
and the assignment (=) operator (BYTEMAN-81), with the usual Java syntax 
and semantics. assignment can be used to modify the value of all rule 
bindings

     * variables introduced in the BINDS clause
     * trigger method local variables: $i, $myString etc
     * trigger method parameters: $1, $myParam (but not $this/$0 which 
is implicitly final)
     * the stacked trigger method return value: $! (only available in AT 
EXIT rules)


note also that in the latter three cases assignment does not just reset 
the value used to resolve references in subsequent rule expressions. it 
also updates the local state of the trigger method. the assigned values 
will be employed on resumption of the method to resolve references to 
local or parameter variables or to supply the result returned to its caller.
