Desc.getClazz(String) should throw RuntimeException with more descriptive message ---------------------------------------------------------------------------------- Key: JASSIST-45 URL: http://jira.jboss.com/jira/browse/JASSIST-45 Project: Javassist Issue Type: Feature Request Environment: Javassist 3.7.0 Reporter: Martin Burger Assigned To: Shigeru Chiba The method javassist.runtime.Desc.getClazz(String) throws an RuntimeException if the given class name cannot be resolved. The message of that exception is "$class: internal error". So, if that exception is thrown in an own project, the developer hasn't a clue about the reason. I suggest the following message: public static Class getClazz(String name) { try { return getClassObject(name); } catch (ClassNotFoundException e) { throw new RuntimeException( "$class: internal error, could not find class '" + name + "' (Desc.useContextClassLoader: " + Boolean.toString(useContextClassLoader) + ")", e); } } The message should include the state of Desc.useContextClassLoader to warn the developer that there could be a problem with different class loaders. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
