Related JCP Specifications

Name	JSR	Description
Java TV API	927	Provides access to digital television services: Audio/video streaming Conditional access Access to in-band and out-of-band data channels Access to service information Tuner control for channel changing On-screen graphics control Media synchronization Application life-cycle management
Connected Device Configuration	36	Supports connected devices like smart phones, set-top boxes and office equipment.
Foundation Profile(FP)	46	Provides application support classes (such as network and I/O) for platforms without a standards-based GUI system. This JSR also includes specifications for three security optional packages.
Personal Basis Profile (PBP)	129	Provides a standards-based GUI framework for supporting lightweight components. It provides the same application support classes as FP, and adds support for the xlet application model.

The Heap: This is the memory used to store your objects and is controlled by the -Xms and -Xmx parameters. The Stack: This is the memory used to store the stack frames for the threads that your program maintains and can be controlled with the -Xss parameter. Permgen Memory: This is the memory used to store your compiled classes and pooled strings as well as some other things and can usually be controlled with -XX:MaxPermSize although the -XX represents a debugging parameter, so there's no guarantee it's on all JVM's. But, the default Sun/Oracle reference implementations have always had them. JNI Allocated Memory Any classes utilizing native methods and JNI could potentially allocate unlimited memory. This memory comes from the OS and not the heap and there's no way of knowing how much memory a native class will use without having access to the source.
