Deep understanding of the JVM reading notes

At present, just the first few chapters of the book, the JVM's memory partition brief description, garbage collection algorithm, garbage collector, commonly used commands and tools to explain. The use of commands and tools to find a time needs to be explained in detail by steps.

Part of the content is an example of how the bytecode instructions look, you can have a general understanding.

The Order of class loading and the ClassLoader have an approximate description, which can be used to recall and understand the specific content of the graph.

At the same time the virtual machine bytecode instruction executes the engine part because the content is more, at the same time the drawing is more difficult to contain, needs to summarize separately.

The early and late optimization part of the program compilation has not thoroughly understand, need to study carefully, understand later can be summarized.

The Java memory model and thread, thread safety, and lock optimization sections can be used as a primer to read and think, while recommending a "Java Concurrent programming Art", just a very coarse browsing, feel the content is more profound, you can understand.
