This guide helps you to troubleshoot issues that might occur with Java Client applications created on the Java Platform, Standard Edition (Java SE) and on Java HotSpot VM. The document provides a description of the available tools and command-line options that can help in analyzing problems. The document also provides guidance to debug core library and client issues and approaches some general issues, such as crashes, hangs, and memory leaks. Finally, the document provides directions for data collection and bug report preparation.
The target audience for this document comprises developers who are using the Java Development Kit (JDK), which is Oracle's implementation of the Java Platform, Standard Edition (Java SE). The current release is Java SE 8 and JDK 8; however, most of the information in this document can be applied to previous releases.
This document is intended for readers with a detailed understanding of the Java Client technologies, a high-level understanding of the components of the Java HotSpot VM, as well as some understanding of concepts such as garbage collection, threads, and native libraries. In addition, it is assumed that the reader is reasonably proficient with the operating system where the Java application is developed and run.
