Steinar Bang commented on SHIRO-537:
------------------------------------
I tried to use the workaround mentioned in this bug, and in the linked-to
stackoverflow answer, but the activator still failed with the same stack trace.
With the workaround in place, the activate method looked like this:
{code:java}
@Activate
public void activate(BundleContext ctx) {
BundleWiring wiring = ctx.getBundle().adapt(BundleWiring.class);
ClassLoader bundleClassloader = wiring.getClassLoader();
Thread current = Thread.currentThread();
ClassLoader originalClassloader = current.getContextClassLoader();
current.setContextClassLoader(bundleClassloader);
try {
IniWebEnvironment webenvironment = new IniWebEnvironment();
webenvironment.setIni(INI_FILE);
webenvironment.setServletContext(getServletContext());
webenvironment.init();
DefaultWebSecurityManager securityManager =
(DefaultWebSecurityManager) webenvironment.getSecurityManager();
UkelonnRealm realm =
createRealmProgramaticallyBecauseOfShiroIniClassCastException();
securityManager.setRealm(realm);
setSecurityManager(securityManager);
setFilterChainResolver(webenvironment.getFilterChainResolver());
} finally {
current.setContextClassLoader(originalClassloader);
}
}
{code}
I've debugged into the activator, using remote debugging from eclipse into
apache karaf. And I have verified that a BundleContext is injected, and a
BundleWiring is successfully retrieved, and the classloaders are successfully
retrieved and replaced.
The activator fails (as before adding the workaround), when the
IniWebEnvironment() constructor tries to create a WebIniSecurityManagerFactory
instance using reflection.
The stack trace in karaf.log with the workaround in place, is:

> Class load issue in OSGI in ClassUtils
> --------------------------------------
>
> Key: SHIRO-537
> URL: https://issues.apache.org/jira/browse/SHIRO-537
> Project: Shiro
> Issue Type: Bug
> Affects Versions: 1.2.3
> Environment: OSGi Felix 4.0.3
> Reporter: Tom Nelson
> Priority: Major
>
> I had the same issue that is described in:
> http://stackoverflow.com/questions/20653146/how-to-load-class-in-an-osgi-e4-environment-while-using-shiro
> where it was suggested a bug was entered but never was, so here it is. A
> similar workaround worked for me:
> Thread currentThread = Thread.currentThread();
> ClassLoader originalCl = currentThread.getContextClassLoader();
> try {
> Class<?> clazz = ((InfrastructureServer)
> server).getBundleContext().getBundle()
>
> .loadClass(CustomRolePermissionResolver.class.getName());
> ClassLoader bundleClassLoader = clazz.getClassLoader();
> currentThread.setContextClassLoader(bundleClassLoader);
> webappContext.deploy(httpServer);
> } catch (ClassNotFoundException e) {
> // TODO Auto-generated catch block
> e.printStackTrace();
> } finally {
> currentThread.setContextClassLoader(originalCl);
> }
> In addition, commons-collections 3.2.1 must be used in an OSGi environment, I
> suggest bumping your dependency.
