These two general "bugs" have wide scope covering at least every Exception
class, and possibly other classes in the JNDI packages

There is inadequate specification of format of toString methods in
ALL exceptions (java.naming.* and java.naming.directory.*).
This enables nonfunctional implementations that do not fulfill
the intent of the method, especially in:

java.naming.NamingException and subclasses

java.naming.CannotProceedException

java.naming.LinkException and subclasses

java.naming.directory.AttributeModificationException

each description should contain a mention of the information
conveyed by the method as well as the format of this information.
This aids product testing efforts as well as
enabling JCK tests to be written. Note also usability is greatly
improved for the end user.


Behavior in null-reference cases is not described in most exception
methods. See also "toString" and its various cases in any
and all exception classes, especially AttributeModificationException
