Rich Mayfield commented on CONFIGURATION-465:
---------------------------------------------

Thanks for the response.  By default, packages listed in the MANIFEST.MF Import-Package header is considered required.  You can, however, make package imports "optional" in cases like you have described.

If it is the case that the class that references Jexl (ExprLookup) is never loaded via the bundle classloader for commons-configuration, then making that package dependency optional should do the trick.

>    Affects Versions: 1.7

> I updated to use commons-configuration 1.7 (from 1.6) and am running into the following resolution error under Eclipse Equinox OSGi framework.
>         An Import-Package could not be resolved. Caused by missing constraint in bundle <org.apache.commons.configuration_1.7.0>
>              constraint: <Import-Package: org.apache.commons.jexl; version="0.0.0">
> According to the Import-Package header in 1.7's MANIFEST.MF, commons-configuration now has a required dependency on org.apache.commons.jexl.  Problem is, there is no OSGi enabled version of Apache Commons jexl that exports this package.
> In jexl 2.0 the packages were renamed and org.apache.commons.jexl2 is exported.  The 1.x codeline, although using org.apache.commons.jexl, does not have the appropriate MANIFEST.MF headers to be used as an OSGi bundle.
> As such, you cannot consume commons-configuration 1.7 in an OSGi environment.
