Suggestions are welcome. > This issue seems related: > https://issues.apache.org/jira/browse/SHIRO-537 I tried to use the workaround mentioned in the above issue, and also in this stackoverflow answer: https://stackoverflow.com/a/20654110 But it still fails. See stack trace from karaf.log at the end. With the workaround in place, the activate method looks like this: @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); } } I've debugged into the code and a BundleContext is injected, and a BundleWiring is successfully retrieved, and the classloaders are successfully retrieved and replaced. It fails when the IniWebEnvironment() constructor tries to create a WebIniSecurityManagerFactory instance using reflection. The stack trace in karaf.log, is: 2018-11-24T11:48:41,006 | ERROR | Thread-50 | security | 171 - no.priv.bang.ukelonn.web.security - 1.0.0.SNAPSHOT |
