classloading error after defining package prefixes [message #145790]

Hello,

I began adding

<packages prefixes="my.package.prefix"/>

elements to certain libraries in my plugin.xml. after doing this,
classes from those libraries that did *not* have these elememts declared
could not be loaded any longer.

is this a bug or a feature, or am I missing something?

thanks,
Christian

A feature to improve class loading: you have to list all package
prefixes of the library. Those not being declared are not found.

did you get what I meant? Let me give an example

<library file="bla.jar"/>
<library file="another.jar">
<packages prefixes="com.mycomp.dada"/>
</library>

after declaring the prefixes for library "another.jar", the classes from
library "bla.jar" were no longer found. Feature?

thanks,
Christian

From your original post it was not clear (at least to me) whether the
*not* belongs to the classes or library. It would have been clearer with
the example attached along with the first posting ;-).

No, this would clearly be a bug. Looks like the class loader uses
prefixes for all libs if prefixes are given for one lib. Please file a
bug report against Platform Core.
