Memory Analyzer Open Source Project
The Eclipse Memory Analyzer is a fast and feature-rich Java heap analyzer that helps you find memory leaks and reduce memory consumption. Use the Memory Analyzer to analyze productive heap dumps with hundreds of millions of objects, quickly calculate the retained sizes of objects, see who is preventing the Garbage Collector from collecting objects, run a report to automatically extract leak suspects.
Eclipse Memory Analyzer (MAT) - Java Code Geeks
In times past, when it came to tracking down sporadic memory problems in a complex Java application, it required using a commercial product such as JProbe or a lot of painful and inefficient attempts to recreate the issue. Even if the problem were easy to recreate, unless the problem was blatantly obvious, your application might need to be enhanced in an iterative fashion to collect sufficient information to begin to diagnose the problem. And don’t make the rookie mistake of assuming the class/method/line that threw the OOM is your problem area. That just happens to be the code that couldn’t obtain the necessary memory.
vFabric tc Server, the best place to build and run Java Spring applications, provides enterprise users with the lightweight server they want paired with the operational management, advanced diagnostics, and mission-critical support capabilities businesses need. Designed to be a drop-in replacement for Apache Tomcat, vFabric tc Server ensures a seamless migration path for existing custom-built and commercial software applications already certified for Tomcat. vFabric tc Server’s built-in Spring instrumentation accelerates development and deployment by as much as 50% over traditional JEE servers. This 100% Apache Tomcat compatible enterprise application server is engineered for Spring and purpose-built for VMware vSphere virtualization.

Introducing tc Server Developer Edition – with Spring Insight | SpringSource Team Blog
We are proud to present the Spring community with a new tool which helps get their applications to production even faster: tc Server Developer Edition is the standard 100% Tomcat you know and love, plus a new Spring Insight console. Spring Insight gives deep visibility into your application’s real activity on a request-by-request basis. For any request you can see all the JDBC queries it made, how much time it took to render, or timings for any of your major Spring beans.
JMeter - Apache JMeter™
The Apache JMeter™ desktop application is open source software, a 100% pure Java application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions. What can I do with it?
