     * Creates JVM instance for given java home. Attempts to validate if provided javaHome is a valid jdk or jre location.

====

As another example, you can configure the _Java Home_ for a task as follows:

====
include::sample[dir="snippets/java/toolchain-config-task/kotlin/",files="build.gradle.kts[tags=java-home]"]
include::sample[dir="snippets/java/toolchain-config-task/groovy/",files="build.gradle[tags=java-home]"]
====

If you require a path to a specific tool such as Java compiler, you can obtain it as follows:

        }

        then:
        home.file(theOs.getExecutableName("jre/bin/javadoc")).absolutePath ==
            Jvm.forHome(home.file("jre")).getExecutable("javadoc").absolutePath
    }

    def "finds tools.jar if java home supplied"() {
        System.properties['java.vm.vendor'] = 'Sun'

        when:
        def home = tmpDir.createDir("home")
        home.create {
            jdk {

        // file
        assertUrlLink("file:/home/taro/test.txt", //
                "file://home/taro/test.txt");
        assertUrlLink("file:/home/taro/あ.txt", //
                "file://home/taro/あ.txt");
        assertUrlLink("file:/home/taro/%E3%81%82.txt", //
                "file://home/taro/あ.txt");

        // smb->file
        assertUrlLink("smb:/home/taro/test.txt", //
                "file://home/taro/test.txt");
