I get the following stack trace for all Shiro filters: https://gist.github.com/steinarb/faa44f384b330ae0259cc051036885db
The error message is: org.apache.shiro.config.ConfigurationException: Unable to instantiate class [org.apache.shiro.web.filter.authc.PassThruAuthenticationFilter] for object named 'authc'. Please ensure you've specified the fully qualified class name correctly. This is the code parsing the INI file: https://github.com/steinarb/oldalbum/blob/master/oldalbum.web.security/src/main/java/no/priv/bang/oldalbum/web/security/OldAlbumShiroFilter.java#L42 This is the INI file being parsed: https://github.com/steinarb/oldalbum/blob/master/oldalbum.web.security/src/main/resources/shiro.ini This being OSGi, I suspected a classloader issue. Shiro tries several classloaders: https://github.com/apache/shiro/blob/main/lang/src/main/java/org/apache/shiro/lang/util/ClassUtils.java#L153 The classloaders tried, are: 1. Thread.currentThread().getContextClassLoader() 2. ClassUtils.class.getClassLoader() 3. ClassLoader.getSystemClassLoader() Alternative 1. looks like it should work, if the parsing code is called from an OSGi bundle that imports package org.apache.shiro.web.filter.authc (and where there is another bundle that exports that package). Alternative 2, could have worked if the shiro-lang bundle had imported package org.apache.shiro.web.filter.authc (which it doesn't) Alternative 3 won't find anything in OSGi. None of my filter bundles imported package org.apache.shiro.web.filter.authc so the first thing I've done is to explicitly add that package to the bundles' import-packages: https://gist.github.com/steinarb/e70d8f4247998344b601c88fdbe27c41#file-pom-xml-L150 But that didn't help: I still get the error messages like https://gist.github.com/steinarb/faa44f384b330ae0259cc051036885db But I see that all shiro filter bundles are in Waiting https://gist.github.com/steinarb/a203fff8fdc183abe97dbe64ccffb012#file-gistfile1-txt-L77 As far as I can tell, the package org.apache.shiro.web.filter.authc was resolved...? https://gist.github.com/steinarb/9c4454baad69e4762ebeb1d05a9db89c#file-gistfile1-txt-L36 I don't know why the bundles are in Waiting? Is it because SCR components couldn't be started? (because they crashed) Tips and hints and ideas appreciated! Thanks! - Steinar
