J9 Java Virtual Machine • Fully compliant (1.3/1.4/1.5) / "Java Powered" (J2ME) and J2SE runtime • Highly configurable class library implementation • Multi-platform • Production level code – shipping now • IBM Websphere Studio Device Developer (WSDD) product V5.5 • IBM JDK 1.3.1 and 1.4.2 • x86, AMD64 Windows and Linux • WebSphere Studio Application Developer 5.1 • WebSphere Application Server – 5.1

14. Java 2 MicroEdition (J2ME) in a Nutshell • Java for the embedded market, in particular Cell phones • J2SE libraries (currently > 35Mb) just didn’t seem to fit on Cell phone • configurable library sizes to meet differing needs of Cell phone makers and carriers • Specifications are developed through the Java Community Process (JCP – www.jcp.org) • controlled by Sun (as Java steward) and they run a process for Java changes and enhancements • Anyone can submit a Java Specification Request (JSR) and produce new Java API’s for various Java platorms (J2SE/EE/ME). • IBM has been and is involved very heavily in the JCP as leaders and participants Basic text slide

15. Configurations and Profiles • A Configuration is a set of classes (non-UI) providing a base set of functionality • Specific classes from java.lang, java.io, java.util, etc. • Currently there 3 finished and 1 under spec development • Connected Limited Device Configuration (Small, minimal VM) • Connected Device Configuration (Larger, standard VM) • JSR-30 CLDC 1.0, JSR-036 CDC 1.0, JSR-139 CLDC 1.1, JSR-218 CDC 1.1 • A Profile is a set of classes (can also be UI related) which can stack on top of a Configuration which can stand alone if needed • You can combine multiple profiles together • There are numerous profiles • JSR-037 MIDP 1.0, JSR-046 Foundation 1.0, JSR-118 MIDP 2.0, … • An optional package is a set of classes which extend either a configuration or profile and extends the functionality • JSR-075 PIM and FileConnection, JSR-082 Bluetooth, JSR-135 MMAPI Basic text slide

22. VM Local Storage • JVM-local storage Used for globals JNI code made re-entrant per VM (no statics) • Exploitation of this feature requires class libraries to support re-entrant natives virtualized (per process) resources Code page, colour defaults … • access via JNIEnv in native code • Also reached via TLS • Only attach one vm per thread • Stacked attachments for recursive attach

23. Garbage Collection (GC) • Four (accurate) GC implementations with Thread Local Heap (TLH) • Generational scavenger (write barriers req'd) • Mark & sweep - full stop and optional compact • 3-colour concurrent incremental (write barriers req'd) • Predictable, low latency, user callable (with bounds) • Large Heap/Parallel GC • Mix and Match GC strategies • Highly configurable through the invocation API or command line • Nursery size • Tenure size + increment • Memory maximum • Remembered set size • TLH parameters
