Description Jaroslav Tulach 2013-11-03 12:51:52 UTC
JDK5 came with generic support for instrumentation:
it however requires changes to the way one invokes Java.

NetBeans Platform also needs such kind of patching from time to time, yet it would be better to do it in a modular way. E.g. be able to define a module which can provide transformation behavior which would then be applied to other loaded classes.
Comment 1 Jaroslav Tulach 2013-11-03 12:52:51 UTC
It would be nice to reuse the API already defined by java.lang.instrument package.
Comment 2 Jaroslav Tulach 2013-11-03 13:00:19 UTC
Basic implementation:

Y01 Need support for OSGi in Equinox mode

Y02 Need documentation and a use-case description in arch.xml

Re. Y01: Netbinox now supported:
Comment 4 Jaroslav Tulach 2013-11-06 14:17:58 UTC
Intended usage can be seen in following OSGi bundles:
one of them defined Agent-Class and hopes that every module/bundle that depends on it will be processed by its JsAgent class.

I fixed the documentation. Unless there are objections I integrate tomorrow:

Merged as 6869874b14af to core-main.
