It requires the following components:

 Javassist. (http://www.csg.is.titech.ac.jp/~chiba/javassist). Version 3.8.1 or greater.

 Objenesis. (http://code.google.com/p/objenesis). Version 1.0 or greater.

 Cglib. (http://cglib.sourceforge.net). Version 2.2 or greater.

To build the extensions:

 Easymock/Easymock Class Extension. (http://easymock.org). Version 2.4 or greater.

To run the tests:

 Easymock/Easymock Class Extension.

 JUnit (http://www.junit.org). Version 4.5 or greater.

To run the extensions tests:

To build Weaver, edit the build.properties file and fill in the
location of the required jars. The ant target "all" will build the
main jar plus the extensions, and run all the tests.


The MapDB group have been using Thread Weaver, and have produced a 
Mavenised version. For details of this, and for a discussion of the
issues that they have had with the framework, see
