Apache KIE is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects.

Java Memory Management Explained | DigitalOcean
Introduction Efficient memory management is critical to building reliable, high-performance Java applications. The Java Virtual Machine (JVM) handles memory allocation and garbage collection automatically, but understanding how memory is structured and managed under the hood is essential for diagnosing issues, tuning performance, and writing optimized code.

GCViewer
GCViewer (download) is a free open source tool to visualize data produced by the Java VM options -verbose:gc and -Xloggc:<file>. It also calculates garbage collection related performance metrics (throughput, accumulated pauses, longest pause, etc.). This can be very useful when tuning the garbage collection of a particular application by changing generation sizes or setting the initial heap size.
