The Java programming language and the Java virtual machine (JVM) is designed to support concurrent programming. All execution takes place in the context of threads. Objects and resources can be accessed by many separate threads. Each thread has its own path of execution, but can potentially access any object in the program.
For the execution of a single thread, the rules are simple. The Java Language Specification requires a Java virtual machine to observe within-thread as-if-serial semantics. The runtime (which, in this case, usually refers to the dynamic compiler, the processor and the memory subsystem) is free to introduce any useful execution optimizations as ...
Eclipse OpenJ9 (previously known as IBM J9) is a high performance, scalable, Java virtual machine (JVM) implementation that is fully compliant with the Java Virtual Machine Specification. [ 3 ] OpenJ9 can be built from source, or can be used with pre-built binaries available at the IBM Semeru Runtimes project for a number of platforms including ...
OpenJDK (Open Java Development Kit) is a free and open-source implementation of the Java Platform, Standard Edition (Java SE). [2] It is the result of an effort Sun Microsystems began in 2006, four years before the company was acquired by Oracle Corporation.
Note that Java EE runs on the standard Java SE JVM but that some vendors specialize in providing a modified JVM optimized for Java EE applications. Much Java development work takes place on Windows, Solaris, Linux, and FreeBSD, primarily with the Oracle JVMs. Note the further complication of different 32-bit/64-bit varieties.
jps – Java Virtual Machine Process Status Tool lists the instrumented HotSpot Java Virtual Machines (JVMs) on the target system. (experimental) jrunscript – Java command-line script shell. jshell – a read–eval–print loop, introduced in Java 9. jstack – utility that prints Java stack traces of Java threads (experimental)
The JVMTI is a native interface of the JVM. A library, written in C or C++, is loaded during the initialization of the JVM. [2] The library has access to the JVM state by calling JVMTI and JNI (Java Native Interface) functions and can register to receive JVMTI events using event handler functions that are called by the JVM when such an event ...
