[jboss-dev] Byteman 1.2.0 release now available

[Andrew Dinn]

Byteman release 1.2.0 has now been released and is available from the 
project downloads page http://www.jboss.org/byteman/downloads.

This release is primarily a feature upgrade extending the Byteman rule 
language to support two new types of rules:

interface rules
-- rule code is injected through an interface into all classes which 
implement the interface

overriding rules
-- rule code is injected down class hierarchies into a both the target 
class's method and into the methods of subclasses which provides an 
overriding implementation

These two new modes of injection may be used in isolation but they also 
work in combination. For example, the following rule adds trace code to 
the run method of every implementor of Runnable and to every overriding 
implementation, effectively tracing every run() operation in the JVM.

RULE trace any Runnable.run() call
INTERFACE ^java.lang.Runnable
METHOD run()
IF TRUE
DO System.out.println("Running runnable " + $0 +
                        " " + $0.getClass().getName())
ENDRULE
	

Full details of the syntax and operation of these two new rule types are 
included in the 1.2.0 programmers guide.

The release also includes several bug fixes including, most notably, a 
much more reliable implementation of tool bytemancheck, which performs 
offline rule syntax and type checking. Release notes are available from 
the project downloads page http://www.jboss.org/byteman/downloads.
