About us
The Garden State Java User Group, Inc. (formerly the ACGNJ Java Users Group), in continuous operation since February 2001, is a 501(c)(3) non-profit organization that provides a forum to promote the use of Java platforms, APIs, and language. We strive to facilitate interactive discussions and exchange of ideas relating to the application of Java.
Topics will primarily focus on JVM technologies such as Java EE, Jakarta EE, MicroProfile, Spring, Groovy and Kotlin. Topics on non-JVM technologies such as Meteor, AngularJS, and Rust may occasionally be presented.
We are proud members of the MicroProfile Working Group and the Jakarta EE Ambassadors and have adopted the Jakarta NoSQL specification.
All meetings are generally held on the second Tuesday of the month, but may change due to speaker availability. In-person meetings are usually held at Drew University in Madison, New Jersey. On-line meetings are held via our YouTube channel.

Finding and Crushing Bugs and More with JFR

We are happy to announce that Billy Korando will be our special guest for the July 2026 meeting. He will present "Finding and Crushing Bugs and More with JFR."
Abstract
Some of the most difficult issues a developer will face are slow developing resources leaks, or errors that occur at infrequent intervals. When these happen, finding the root cause can be difficult, and a frequent recourse by developers is to add a lot of logging statements around suspected problem sites. What if I told you there was a better option, and that option already existed right in the JVM you are already running?
JDK Flight Recorder (JFR), as its namesake suggests, is a low-overhead profiling and diagnostic tool that's been built directly into the JDK since JDK 7. In this presentation we are going to look at how developers can leverage JFR's powerful API and reporting tools for tracking down those difficult bugs as well as how JFR can be incorporated into the development process.
