Christoph Läubrich commented on LOGGING-198:
--------------------------------------------

The 1.2 version has sadly the same issue, would it be possible to have a bugfix release for that one as well?

> Currently the manifest of org.apache.commons.logging look like this:
> {code}
> Export-Package                          org.apache.commons.logging.impl;version="1.3.4"
>                                         org.apache.commons.logging;version="1.3.4"
> {code}
> This tells the OSGi resolver that logging and logging.impl are independent packages (e.g. has no references to each other).
> This seems highly unlikely and we have an example where this is causing classpath issues.
> {code}Caused by: java.lang.ClassCastException: The application has specified that a custom LogFactory implementation should be used but Class 'org.apache.commons.logging.impl.LogFactoryImpl' cannot be converted to 'org.apache.commons.logging.LogFactory'. {code}
> To prevent the issue, the export package should contain use clauses, at the minimum {code}uses:="org.apache.commons.logging,org.apache.log,org.apache.log4j"{code} but there could be more used by the impl!
> {code}
> Export-Package                          org.apache.commons.logging.impl;version="1.3.4";uses:="org.apache.commons.logging,org.apache.log,org.apache.log4j"
>                                         org.apache.commons.logging;version="1.3.4"
> {code}
