Joining Java's Hall of Fame

JRuby’s Charlie Nutter becomes Java Champion

The JRuby and JVM guy joins illustrious company after being crowned a Java champion.

Charlie Nutter, one of the leads behind the JVM implementation
JRuby, has been made the newest Java Champion.

Last year’s JAX
Innovation Special Jury Award
winner was given the
honour at the recent JFokus conference, but Oracle officially

acknowledged it only yesterday
. Nutter is described by Java
Developer Community Lead, Tori Wieldt, as “the main force (along
with Thomas Enebo) behind JRuby”.

The bridge-building implementation that has gone from strength to
strength since its creation in 2001, outperforming Ruby itself in

certain benchmark tests
. In 2009, the JRuby core
development team left Sun Microsystems to join Red Hat, before
Nutter and Enebo left last year to join Red Hat.

Nutter isn’t just known as the JRuby guy, but the JVM guy also.
Since the beginning of his involvement, Nutter and his dedicated
team have always wanted their implementation as a first class
citizen on the JVM. Nutter had a pivotal role in getting the
invokedynamic functionality into Java 7, which adds extra support
to dynamic languages on the JVM. Invokedynamic’s arrival gave
parity to the platform, allowing other JVM languages to
thrive. Nutter explains the importance of invokedynamic at
JAXconf 2012 and how it’s shaking up the JVM.


“He continues to work on the JVM for other languages today,
regularly contributing to the hotspot mailing lists and JVM
Language summit etc,” explains Wieldt.

Java Champions are recognised passionate Java technology and
community leaders who are nominated by the wider community. There
are currently around 130 Java
, reading like a Java ‘Hall of Fame’ and Nutter
deserves to be amongst them for his work in bringing two language
communities together.

Congratulations Charlie!
