Java Language Instantiating sun.misc.Unsafe via bootclasspath


Example

public class UnsafeLoader {
    public static Unsafe loadUnsafe() {
        return Unsafe.getUnsafe();
    }
}

While this example will compile, it is likely to fail at runtime unless the Unsafe class was loaded with the primary classloader. To ensure that happens the JVM should be loaded with the appropriate arguments, like:

java -Xbootclasspath:$JAVA_HOME/jre/lib/rt.jar:./UnsafeLoader.jar foo.bar.MyApp

The foo.bar.MyApp class can then use UnsafeLoader.loadUnsafe().
