2019 February Meeting

March 5th, 2019 Comments off

When: Tuesday, February 12, 2019   11:30 – 13:00

Where: StarSpace46  1141 W. Sheridan Avenue

Topic: Essential Tools for Performance Metrics and Troubleshooting

Every developer creating real-world applications will have to eventually troubleshoot code performance issues – sometimes even in Production systems. In this session we will show a couple of essential tools that every Java developer should know about and can use to gather detail performance metrics (CPU, Memory, Threads, Hot Methods, etc.). With the help of these tools you can get to the bottom of tough issues such as bottlenecks caused by locking and memory leaks. We will specifically cover Java Mission Control (JMC), and Eclipse Memory Analyzer Tool (MAT).

Speakers:

Bill Spens is Director of Software Development at Power Costs, Inc. (PCI); He has 10 years of experience troubleshooting Java and Oracle performance and currently focuses on improving processes and efficiency across many agile teams.

John Chesser has been writing Java on the front and back end for 18 years. John focuses on keeping it simple. He has experience writing full systems from scratch and maintaining older systems for companies like Creative Labs Inc. and Powercosts Inc.

Topic: Java 9 Modules: What’s the Hype All About?

One of the biggest hypes about Java 9 is the Java Platform Modular System (JPMS) or Project Jigsaw. Modules give us 3 core principals:

  • Strong Encapsulation
  • Stable Abstraction
  • Explicit Dependencies

In this talk we will discuss the history of JPMS, look at some of its core features and do some demos.
