Chapter 8. Additional JNI Features

We have discussed the JNI features used for writing native methods and embedding a Java virtual machine implementation in a native application. This chapter introduces the remaining JNI features.

JNI and Threads

The Java virtual machine supports multiple threads of control concurrently executing in the same address space. This concurrency introduces a degree of complexity that you do not have in a single-threaded environment. Multiple threads may access the same objects, the same file descriptors—in short, the same shared resources—at the same time.

To get the most out of this section, you should be familiar with the concepts of multithreaded programming. You should know how to write Java applications that utilize ...
