The JVM
There is a JVM in webOS. His name is OasisVM.
You can have more information when you use this command-line :
root@palm-webos-device:/# javahy --help OasisVM: Build 107 Copyright 2005, Iventor, Inc. All Rights Reserved Build options are: Oasis-Linux-WebConsole-LightLocks-Generational-GCC_Goto_Optimizations-SingleSlot usage: OasisVM [options] [classfile [args]]
Note: OasisVM Build 107 with webos 1.4.1, OasisVM Build 96.2 with webOS 1.1.0 The web server for iventor.com return only 404 errors. We can see a version of this website at www.iventor.com from a couple of years ago. This company was founded by Paul Mercer.
Options in OasisVM Build 107 are :
Options are: -classpath <path> or -cp <path> -bootclasspath <path> or -bcp <path> -h, --help Display help and exit -m, --object-heap-size <num> Set object heap size -s, --vm-stack-size <num> Set java stack size -t, --nm-stack-size <num> Set native methods stack size -Xstacklimit=<num> Set java stack limit -d, run the VM as a daemon -Xms set object heap size (variant) -Xmx set object heap size (variant) -Xnh set native code heap size -Xint interpreter only (disable the JIT) -Xpreload=<filename> file containing list of classes to preload before running main -Xpreloadout=<filename> output file containing list of classes we loaded -verbose:[class|threads|gc|warnings] print extra debugging info -Xprofile print periodic profiler stats -Xgcnocopy use a non-copying garbage collection -Xconservative use conservative collection -Xexact use exact collection -Xtraceall trace all classes (no class unloading) -Xgcagressive agressive garbage collection -Xgcdelay wait X ms before garbage collection begins -Xnoyank disable rug yanking -Xnossa disable SSA optimizations -XnoSSA disable SSA optimizations - -nojit synonym for -Xint -Xrandcomp random JIT compiles -Xbreak debug break after initializing the VM -Xbootbreak debug break before initializing the VM -XX:+HeapDumpOnOutOfMemoryError dump heap to oom.hprof on OOM error -Xstackdump=<filename> - -ms enable memory stats -Xxray=fifoname enable xray output -Xwebconsole enable web console at 127.0.0.1:8083

The Java Classes
The OasisVM JVM in webos use Java Classes from Harmony to Implement the Java Platform Standard Edition 5.
In webOS 1.4.1 for Harmony and OasisVM versions, we have : root@palm-webos-device:/# ipkg list | grep harmony harmony - 5.0.r603534-67 - harmonykernel - 1.0.0-21 - oasisharmonyvm - 1.0-107 -
Note : revision 603534 was commit in the Harmony SVN the 12th December 2007 and Harmony 5.0 M4 stable was release the 2007-12-19 (History relases here).
The revision 603534 for Harmony is old, more than 2 years, and there was improvements in Harmony :
- 5.0 M6 with new JIT optimizations, improved VM threading design
- 5.0 M9 with performance: across multiple areas, including class library improvements and JIT compiler global propagation optimizations, integer MUL/DIV/REM strength reduction,
