I've already added tools.jar in classpath, why still java.lang.NoClassDefFoundError: com.sun.jdi.Bootstrap thrown?

I'm using the HotSwap function of javassist, it requires tools.jar in classpath, so I added -cp tools.jar when start my OSGi appliction. But when I new HotSwap() in the code of one of the bundles, 

 java.lang.NoClassDefFoundError: com.sun.jdi.Bootstrap

was thrown. com.sun.jdi.Bootstrap is in the tools.jar and I've already added it in classpath and also I verified it worked because if not, the following code will not work:

JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();

The Classloader of HotSwapper cannot load classcom.sun.jdi.Bootstrap? Then why it works properly in my Eclipse environment?(I added tools.jar into the libraries of Build path)

On why NoClassDefFoundError, any clue is appreciated.

Solution

  • In Equinox, you can set Boot Delegation to * to gain acess to all class in bootclass, see this wiki for details. In 3.2, it was osgi.compatibility.bootdelegation=true in config.ini.
