Auf Codesnips können Sie CodeSnippets zu verschiedensten Programmiersprachen finden. Außerdem gibt es eine Sammlung von Tutorials., Dieses Tutorial beschäftigt sich mit Java, JAXB und dem Ant Task für die Erzeugung der Wrapper-Klassen für JAXB.
This document is a guide to help troubleshoot problems that might arise with applications that are developed using the Sun Microsystems Inc. release of Java Platform, Standard Edition 6 (JDK 6 release or Java SE 6 release). In particular, this guide addresses possible problems between the applications and the Java HotSpot virtual machine. The document provides a description of the tools, command line options, and other help in analyzing a problem. The document also provides guidance on how to approach some general issues such as a crash, hang, or memory resource issues. Finally, the document provides direction for data collection and bug report preparation.
The following table shows the values that are used when -XX:+UseContainerSupport is set:
Less than 1 GB 50% <size>
1 GB - 2 GB <size> - 512 MB
Greater than 2 GB 75% <size>
The default heap size is capped at 25 GB
The default heap size for containers takes affect only when the following conditions are met:
The application is running in a container environment.
The memory limit for the container is set.
The -XX:+UseContainerSupport option is set, which is the default behavior.
