    Overrides:
      `transformMetaMethod` in class `Java8`
    Parameters:
      `metaClass` - metaclass
      `metaMethod` - the original meta method
      `caller` - caller class, whose method sets accessible for methods
    Returns:

  - ### trySetAccessible

    public boolean trySetAccessible(AccessibleObject ao)
    Deprecated, for removal: This API element is subject to removal in a future version.
    Description copied from interface: `VMPlugin`
    Set the `accessible` flag for this reflected object to `true` if possible.
    Specified by:
      `trySetAccessible` in interface `VMPlugin`

    Parameters:
      `ao` - the accessible object
    Returns:
      `true` if the `accessible` flag is set to `true`; `false` if access cannot be enabled.

  - ### checkCanSetAccessible

    public boolean checkCanSetAccessible(AccessibleObject accessibleObject, Class<?> callerClass)
    Deprecated, for removal: This API element is subject to removal in a future version.
    This method may be used by a caller in class C to check whether to enable access to a member of declaring class D successfully if `Java8.checkCanSetAccessible(java.lang.reflect.AccessibleObject, java.lang.Class)` returns true and any of the following hold:

    1) C and D are in the same module. 2) The member is public and D is public in a package that the module containing D exports to at least the module containing C. 3) The member is protected static, D is public in a package that the module containing D exports to at least the module containing C, and C is a subclass of D. 4) D is in a package that the module containing D opens to at least the module containing C. All packages in unnamed and open modules are open to all modules and so this method always succeeds when D is in an unnamed or open module.

    Specified by:
      `checkCanSetAccessible` in interface `VMPlugin`
    Overrides:
      `checkCanSetAccessible` in class `Java8`
    Parameters:
      `accessibleObject` - the accessible object to check
      `callerClass` - the class wishing to invoke `setAccessible`
    Returns:
      the check result

  - ### checkAccessible

    public boolean checkAccessible(Class<?> accessingClass, Class<?> declaringClass, int memberModifiers, boolean allowIllegalAccess)
    Deprecated, for removal: This API element is subject to removal in a future version.
    Description copied from interface: `VMPlugin`
    check whether the member can be accessed or not
    Specified by:
      `checkAccessible` in interface `VMPlugin`
    Overrides:
      `checkAccessible` in class `Java8`
    Parameters:
      `accessingClass` - callerClass the callerClass to invoke `setAccessible`
      `declaringClass` - the type of member owner
      `memberModifiers` - modifiers of member
      `allowIllegalAccess` - whether to allow illegal access
    Returns:
      the result of checking
