One plugin exporting packages from jars inside itself [message #330559]

Hi,

I have a plugin where I put the jboss client jars that my application uses.
I then export the packages from this jars.

But today, looking at the help documentation of the Manifest / Runtime page,
I saw this:

"Since JAR'd plug-ins are the recommended format for Eclipse 3.1 and up
built plug-ins, it is recommended to leave this section blank."

Is it a bad practice to have one plugin exporting packages from jars inside
it?

If yes, somebody can tell me the best way to do this?

Thanks in advance,

Marcelo

I'm not sure if it is "bad practice" or not, but there are a couple of
things to consider:
1) The JDT compiler can't compile against nested jars, therefor you may
have issues at build time. (One of the bugs here is :
https://bugs.eclipse.org/bugs/show_bug.cgi?id=157375)

2) The nested jars will be extracted at runtime by the OSGi framework
and place in a cache. This could potentially impact startup performance.
