Скачать или смотреть JVM Debugging under the Hood

If you are like me, then the debugger is your absolute favourite tool. But how does the Java debugger really work ? For instance, why do some conditional breakpoints severely slow down the code? We will look at how the debugger and the JVM interact to carry out common tasks such as: - breakpoints - stepping - code evaluation - value modification - reference traversal - hot code replacement. Finally, we will experiment with the java debug interface ourselves to improve debugging and capture more precise information: - Record stack frames with values. - specify NullPointerException cause. - live object monitoring. Come along to see the power of the Java debugger unleashed.
