Class Capabilities
public class Capabilities
extends java.lang.Object
The map of extended features supported by the runtime in which we live.
This class should be independent of all other bsh classes!
Note that tests for class existence here do *not* use the
BshClassManager, as it may require other optional class files to be
loaded.
static class | Capabilities.Unavailable - An attempt was made to use an unavailable capability supported by
an optional package.

canGenerateInterfaces
public static boolean canGenerateInterfaces()
classExists
public static boolean classExists(String name)
Use direct Class.forName() to test for the existence of a class.
We should not use BshClassManager here because:
a) the systems using these tests would probably not load the
classes through it anyway.
b) bshclassmanager is heavy and touches other class files.
this capabilities code must be light enough to be used by any
system **including the remote applet**.
haveAccessibility
public static boolean haveAccessibility()
If accessibility is enabled
determine if the accessibility mechanism exists and if we have
the optional bsh package to use it.
Note that even if both are true it does not necessarily mean that we
have runtime permission to access the fields... Java security has
a say in it.
