Example 1 with WeavingException

use of org.osgi.framework.hooks.weaving.WeavingException in project aries by apache.

the class ProxyWeavingHook method weave.

public final void weave(WovenClass wovenClass) {
    BundleWiring bw = wovenClass.getBundleWiring();

    }
    if (!isEnabled(wovenClass.getClassName()) || isDisabled(wovenClass.getClassName())) {

                //can still be loaded
                LOGGER.trace(String.format("The class %s cannot be woven, it may not be possible for the runtime to proxy this class.", wovenClass.getClassName()), e);
            } else {
