Release Notes for Norm
Norm
v2.2.0 Release Notes
Description
"Norm" is the name of the contributed Jini technology lease renewal
service implementation from Sun Microsystems. The River Lease Renewal
Service Specification is available in html.
The specification for Norm is defined not only by the River Lease
Renewal Service Specification, but also by the API documentation
(generated by the Javadoc(TM) tool) for
Administrable.

- Configuration
- In this release, no new configuration entries have been added, nor have any other
changes occurred with respect to the configuration.
A full list of supported configuration entries is given in this service's
man page.
- Logging
- In this release, no changes have occurred with respect to the logging mechanism
employed by Norm, which logs diagnostic information using a separate
Logger
for each type of information logged. The name of each logger
is a dot-separated concatenation of the implementation package name,
com.sun.jini.norm, with a descriptive string. A description
of each
logger used by this service, as well as what information is logged to which
logger, and at what logging level, is given in this service's
man page.
- Bug Fixes of Interest
- A number of bugs have been addressed in this release of Norm.
What follows is a description of those bugs that might be of
interest:
- 4965775: Norm threads should guard against lost interrupts
-
- Thread subclasses in Norm that use logging and do not override the
Thread.interrupt method to set an "interrupted" field are
susceptable to lost interrupts. This problem can occur because
java.util.logging swallows internal
InterruptedIOExceptions without setting the receiving
thread's interrupted status, effectively forgetting the interrupt. The
end result is that some of Norm's threads could loop endlessly instead of terminating, causing Norm shutdowns to hang.
This bug has been fixed.
