James Gosling’s Letter to the Java Community

Dear Java Community,

As you can see, we’re making progress with our plans to open source
Sun’s implementations of the Java platform. I’m happy to see Java
technology embarking on a new journey with this official open-source
licensing announcement.

Java technology has been a cornerstone of software development for
more than a decade now — the community is ready for the next chapter,
and the timing is right. As we stated at the JavaOne conference last
May, the most crucial part of this decision was that we realized
developers want to preserve compatibility, interoperability, and
reliability. We intend to take steps to help make sure Java technology
remains compatible, interoperable, and reliable. And we know the Java
community feels the same way.

We will continue to do an immense amount of testing with the Java
platform. Everything we do will get checked, rechecked, and we will
debug rigorously. We expect that people who care about reliability and
compatibility with the Java specification will continue to use and
enhance Java technology.

One reason Java technology remains so popular is that it’s
remarkably successful at spanning a lot of different domains. You can
write software for application servers, cell phones, scientific
programming, desktop applications, games, embedded software — the list
is endless. We’re intend to maintain the support of this broad span of
domains.

Sun continues to embrace open source, and I invite you to join us.
There are all kinds of contributions you can make. If there’s a bug
that you really care about, you can go work out a fix. (That’s one area
where developers have made tens of thousands of contributions over the
years.) I also invite you to help us add new features. If there’s new
functionality that you really want in Java technology, the process is
there to help you to add that to the platform as well.

Sincerely,
James Gosling

Monitoring and Managing Java SE 6 Platform Application

nice article on monitoring and managing java se 6 was published on java.sun.com/developer.

An application seems to run more slowly than it should or more
slowly than it did previously, or the application is unresponsive or
hangs. You may encounter these situations in production or during
development. What is at the root of these problems? Often, the causes
– such as memory leaks, deadlocks, and synchronization issues — are
difficult to diagnose. Version 6 of the Java Platform, Standard Edition (Java SE) provides you with monitoring and management capabilities out of the box to help you diagnose many common Java SE problems.

This article is a short course in monitoring and managing Java SE 6
applications. It first describes common problems and their symptoms in
a Java SE application. Second, it gives an overview of Java SE 6′s
monitoring and management capabilities. Third, it describes how to use
various Java Development Kit (JDK) tools to diagnose these problems.

Note: Any API additions or other enhancements to the Java SE platform specification are subject to review and approval by the JSR 270 Expert Group.
