        Description

        Currently, if a user-provided taglet throws an exception in an initializer, the exception will be wrapped in ExceptionInInitializerError, which is not caught/handled in TagletManager.addCustomTag, with the result that it is reported as a javadoc crash ... as shown in the following trace.

        javadoc: error - An internal exception has occurred.
        (java.lang.ExceptionInInitializerError)
        Please file a bug against the javadoc tool via the Java bug reporting page
        (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com)
        for duplicates. Include error messages and the following diagnostic in your report. Thank you.

        1 error

        TagletManager should catch/handle all exceptions that may be caused when instantiating user-provided taglets, and cleanly report them as an issue in the taglet code ... and not as a javadoc issue.
