DelegatingBundle optimization
-----------------------------
Key: XBEAN-177
URL: https://issues.apache.org/jira/browse/XBEAN-177
Project: XBean
Issue Type: Improvement
Components: bundleutils
Affects Versions: 3.8
Reporter: Jarek Gawor
Assignee: Jarek Gawor
DelegatingBundle forwards loadClass() (among other functions) to multiple
bundles. Right now the loadClass() implementation iterates over the bundles and
attempts to load the class from each bundle until the class is successfully
loaded.
This method can actually be harmful in certain situations for example with
bundles with DynamicImport-Package: *. It can needlessly establish a dynamic
wired for the given package on each bundle in the list.
One way to avoid this problem is to check (once CNFE is raised) if the given
bundle is wired to some bundle that exports the given package. If so, there is
no need to check the remaining bundles to load the class.
