> Hi,
> Here is the case :
> I have one bundle with a missing import, I need to fix the bundle but Felix
> 3.0.1 is not helping me with the errors that are thrown. (the missing package
> required to start my bundle is "org.apache.juli.logging") and this missing
> package is not reported as a missing package in 3.0.1 while it was reported
> with Felix 2.0.5
> When testing this bundle with Felix 3.0.1, I get the following message :
> org.osgi.framework.BundleException: Unresolved constraint in bundle xxx [89]:
> Unable to resolve 89.0: missing requirement [89.0] package;
> (&(package=org.apache.catalina.tribes.group.interceptors)(version>=7.0.0)) -
> [89.0] package;
> (&(package=org.apache.catalina.tribes.group.interceptors)(version>=7.0.0))
> at org.apache.felix.framework.Felix.resolveBundle(Felix.java:3421)
> at org.apache.felix.framework.Felix.startBundle(Felix.java:1754)
> at org.apache.felix.framework.BundleImpl.start(BundleImpl.java:905)
> This package (org.apache.catalina.tribes.group.interceptors) is present in my
> bundle archive.
> It tells me that a requirement is not available but I don't know which
> package is missing which is a big problem as it's quite difficult to fix an
> issue when there is a missing information
> By switching back to Felix v2.0.5, I have the following error :
> org.osgi.framework.BundleException: Unresolved constraint in bundle xxx [89]:
> package; (package=org.apache.juli.logging)
> at org.apache.felix.framework.Felix.resolveBundle(Felix.java:3299)
> at org.apache.felix.framework.Felix.startBundle(Felix.java:1657)
> at org.apache.felix.framework.BundleImpl.start(BundleImpl.java:905)
> And now, we can see that the missing package is printed
> By adding some breakpoint in Felix 3.0.1, I can see that the original error
> is raised in ResolverImpl class but then this error is ignored
> Here is the code that is raising my expecting missing package :
> if ((candidates.size() == 0) && !req.isOptional())
> {
> ResolveException ex =
> new ResolveException("Unable to resolve " + module
> + ": missing requirement " + req, module, req);
> resultCache.put(module, ex);
> m_logger.log(Logger.LOG_DEBUG, "No viable candidates", ex);
> throw ex;
> }
> The exception which is built here is :
> org.apache.felix.framework.resolver.ResolveException: Unable to resolve 89.0:
> missing requirement [89.0] package; (package=org.apache.juli.logging)
