    - #### getThreadContextHelper

          protected java.lang.Object getThreadContextHelper()

      Description copied from class: `VMBridge`
      Return a helper object to optimize `Context` access.

      The runtime will pass the resulting helper object to the subsequent calls to `VMBridge.getContext(Object contextHelper)` and `VMBridge.setContext(Object contextHelper, Context cx)` methods. In this way the implementation can use the helper to cache information about current thread to make `Context` access faster.

      Specified by:
        `getThreadContextHelper` in class `VMBridge`

    - #### getContext

          protected Context getContext​(java.lang.Object contextHelper)

      Description copied from class: `VMBridge`
      Get `Context` instance associated with the current thread or null if none.
      Specified by:
        `getContext` in class `VMBridge`
      Parameters:
        `contextHelper` - The result of `VMBridge.getThreadContextHelper()` called from the current thread.

    - #### setContext

          protected void setContext​(java.lang.Object contextHelper,
                                    Context cx)

      Description copied from class: `VMBridge`
      Associate `Context` instance with the current thread or remove the current association if `cx` is null.
      Specified by:
        `setContext` in class `VMBridge`
      Parameters:
        `contextHelper` - The result of `VMBridge.getThreadContextHelper()` called from the current thread.

    - #### tryToMakeAccessible

          protected boolean tryToMakeAccessible​(java.lang.reflect.AccessibleObject accessible)

      Description copied from class: `VMBridge`
      In many JVMSs, public methods in private classes are not accessible by default (Sun Bug #4071593). VMBridge instance should try to workaround that via, for example, calling method.setAccessible(true) when it is available. The implementation is responsible to catch all possible exceptions like SecurityException if the workaround is not available.
      Specified by:
        `tryToMakeAccessible` in class `VMBridge`
      Returns:
        true if it was possible to make method accessible or false otherwise.

    - #### getInterfaceProxyHelper

          protected java.lang.Object getInterfaceProxyHelper​(ContextFactory cf,
                                                             java.lang.Class<?>[] interfaces)

      Description copied from class: `VMBridge`
      Create helper object to create later proxies implementing the specified interfaces later. Under JDK 1.3 the implementation can look like:

           return java.lang.reflect.Proxy.getProxyClass(..., interfaces).
               getConstructor(new Class[] {
                   java.lang.reflect.InvocationHandler.class });

      Specified by:
        `getInterfaceProxyHelper` in class `VMBridge`
        `interfaces` - Array with one or more interface class objects.

    - #### newInterfaceProxy

          protected java.lang.Object newInterfaceProxy​(java.lang.Object proxyHelper,
                                                       ContextFactory cf,
                                                       InterfaceAdapter adapter,
                                                       java.lang.Object target,
                                                       Scriptable topScope)

      Description copied from class: `VMBridge`
      Create proxy object for `InterfaceAdapter`. The proxy should call `InterfaceAdapter.invoke(ContextFactory, Object, Scriptable, Object, Method, Object[])` as implementation of interface methods associated with `proxyHelper`. `Method`
      Specified by:
        `newInterfaceProxy` in class `VMBridge`
      Parameters:
        `proxyHelper` - The result of the previous call to `VMBridge.getInterfaceProxyHelper(ContextFactory, Class[])`.
