Among the most celebrated developers in recent years,
especially in the domain of Java EE and JavaFX, is consultant Adam Bien, who, in
addition to being a JavaOne Rock Star for Java EE sessions given in 2009 and
2011, is a Java Champion, the winner of Oracle Magazine’s 2011 Top Java
Developer of the Year Award, and recently won a 2012 JAX Innovation Award as a
top Java Ambassador.
Bien
will be presenting the following sessions:
TUT3907 - Java EE 6/7: The Lean Parts
CON3906 - Stress-Testing Java EE 6 Applications Without
Stress
CON3908 - Building Serious JavaFX 2 Applications
CON3896 - Interactive Onstage Java EE
Overengineering
I spoke with Bien to get his take on Java today. He expressed excitement that the smallest companies and
startups are showing increasing interest in Java EE. “This is a very good sign,” said Bien.
“Only a few years ago J2EE was mostly used by larger companies -- now it becomes interesting
even for one-person shows. Enterprise Java events are also extremely popular. On the Java SE side,
I'm really excited about Project Nashorn.” Nashorn is an upcoming JavaScript engine, developed fully
in Java by Oracle, and based on the Da Vinci Machine (JSR 292) which is expected to be available for
Java 8.
Bien expressed concern about a common misconception regarding Java's mediocre productivity.
“The problem is not Java,” explained Bien, “but rather systems built with ancient patterns and approaches.
Sometimes it really is ‘Cargo Cult Programming.’ Java SE/EE can be incredibly productive and lean without
the unnecessary and hard-to-maintain bloat. The real problems are ‘Ivory Towers’ and not Java’s lack of
productivity.”
Bien remarked that if there is one thing he wanted Java developers to understand it is that,
"Premature optimization is the root of all evil. Or at least of some evil. Modern JVMs and
application servers are hard to optimize upfront. It is far easier to write simple code and
measure the results continuously. Identify the hotspots first, then optimize.”
He advised Java EE developers to, “Rethink everything you know about Enterprise Java.
Before you implement anything, ask the question: ‘Why?’ If there is no clear answer -- just don't do it.
Most well known best practices are outdated. Focus your efforts on the domain problem and not the
technology.”
Looking ahead, Bien remarked, “I would like to see open source application servers running
directly on a hypervisor. Packaging the whole runtime in a single file would significantly simplify
the deployment and operations.”
