Jarek Gawor commented on GERONIMO-6209:
---------------------------------------
I committed the initial code in revision 1195653.
The value returned by TransformerAgent.isRedefineClassesSupported() indicates
whether or not class swap is supported. That usually just queries the JVM
(Instrumentation.isRedefineClassesSupported()) to see if class redefinition is
supported. Since most JVMs do support it and I could not find an easy way to
disable class redefinition support I added a
"org.apache.geronimo.transformer.redefineClasses" system property that can be
used to disable it. That is, the TransformerAgent.isRedefineClassesSupported()
will return false even though Instrumentation.isRedefineClassesSupported() can
return true.
