You didn't set the environment variable CLASSPATH, but a shell variable of this name, i.e. only the shell sees this. What you did here is similar to setting a variable in your Java program, then run a shell program from Java and hope that the Java variable is visible to the shell program.
In shell context, "environment variables" are sometimes also called "exported variables", because the child processes can see them. Each shell has a different way to set an environment variable. For example, bash or zsh use the command export, while csh or tcsh use the command setenv.
You didn't specify, which shell you are using. Consult the man page of your shell to find out, how to set environment variables.

ikvm(1) General Commands Manual ikvm(1)
NAME
ikvm - java virtual machine executable using the CLI runtime
SYNOPOSIS
ikvm [ options ] class [ args ... ]
ikvm [ options ] -jar jarfile [ args ... ]
DESCRIPTION
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 execu-
tion 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.
CLASS SEARCHING
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 con-
tains .
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.
OPTIONS
-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 sep-
arated 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.
-? -help
Display a summary of the usage.
