Java virtual machine executable using the cli runtime
ikvm [ options ] class [ args ... ]
ikvm [ options ] -jar jarfile [ args ... ]
IKVM is an implentation of the Java for the Common Language Infrastructure (CLI) runtime. It includes a byte code JIT compiler/verifier to translate Java byte code to CIL and GNU Classpath to provide the Java class libraries. ikvm program performs this translation and execution at run time, the ikvmc(1) program provides a static compilation to CIL.
This program is intended to act as a drop-in replacement for the java program that executes java bytecode (with or without a JIT) and as such, takes a subset of that tool's options and arguments as given here.
ikvm operates in two modes, either on a fully-qualified Java classname or on a jar file with the -jar jarfile option given. Any remaining arguments args ... are passed to the main class.
Classes are searched for in the current directory if no -cp / -classpath option, no -jar option and no CLASSPATH environment variable is set.
If only CLASSPATH is set and no ptions are given only that is used to find classes, the current directory is not used unless CLSSPATH contains .
If -cp / -classpath is given, CLASSPATH is ignored.
If -jar is given, the jar file is put at the start of the classpath taken from either the -cp / -classpath option or from CLASSPATH.
See also the description for the -Xbootclasspath option below.
-cp path
-classpath path
Set the JVM classpath to search for application classes and resources. The path is a sequence of directories and zip/jar files separated by : (; on Windows). If this option is given more than once, only the last one applies.
-Dname=value
Set a system property name to value.
-ea[:packagename ... | :classname]
-enableassertions[:packagename ... | :classname]
Enable assertions.
-da[:packagename ... |:classname]
-disableassertions[:packagename ... | :classname]
Disable assertions.
-version
Display IKVM and runtime version
-Xbootclasspath:path
Set the boot JVM classpath for bootstrap classes and resources. The path is a sequence of directories and zip/jar files separated by : (; on Windows). If this option is given more than once, only the last one applies.
-Xbreak
Trigger a user defined breakpoint at startup
-Xmethodtrace:string
Builds method trace into the specified output methods
-Xsave
Save the generated assembly for debugging.
-Xtime
Time the execution.
-Xtrace:name
Displays all tracepoints with the given name.
-Xwait
Keep the process hanging around after exit.
