Visualizing the Garbage Collection subsystem of the JVM is often a challenge. In this talk we discuss jfx-mem, a Free JavaFX tool for understanding how memory behaves in the Java heap. It features a discussion of the Java heap & collectors, JavaFX technology & the challenges & joys involved in working with a cross-functional team when building Free software.

The Adopt OpenJDK project is just over 1 year old. We will review where we came from, whence we spent our effort & where we’re going. The next 12 months represents, in our view, the most amazing time for developers to get involved in the platform. This is going to be brilliant.

Perl is wonderful, idiosyncratic & occasionally crazy-making. In this talk, Ben will share the lessons he learned from the Perl language & community, and how he has tried to apply them in the Java & JVM communities, and to ask the question of how communities can do more to co-operate & learn from each other.

In 2011 the London Java Community (LJC) stood for, and overwhelmingly won a seat in the open elections for a seat on the JCP Executive Committee (JCP EC), enough acronyms yet? We haven't even started! It's been a whirlwind trip so far with a great deal learned about politics, acronyms, the due diligence required on a JSR, flights to exotic places (Jersey City!?), wrangling over the wording of a sentence and of course launching some developer lead initiatives. There have of course been some great successes in moving Free Java forward such as the JSR-348 which is the start of reforming the JCP and JSRs towards a truly open and transparent model. This talk covers the good works done so far, some anecdotes of what it's like to work as a developer amongst a mix of technologists and bearucrats and what we think is left to be done.

What the audience will learn from the talk: An insight to how the JCP really works and the surprising fact that Oracle and the other large corporates are generally pushing for a Free Java. How can people help out with the project, what feedback are you looking for? We want people to start supporting the JCP again and working with it to change it for the better, JSR-348 has proven that steps can be taken although we recognize there is still a long way to go.
