Description

Groovysh lets you set & read private member fields, as long as they're static:

groovy> class C

{ private static x }

groovy> C.x = new Integer(10)
groovy> println C.x
groovy> go
10

Note that it doesn't let you access regular private fields:

groovy> class B

{ private x }

groovy> b = new B()
groovy> b.x = new Integer(10)
groovy> go
Caught: groovy.lang.IllegalPropertyAccessException: Can not access the
private field x in class B

With jsr-03, IllegalPropertyAccessException has been thrown.
But with the current jsr-04-SNAPSHOT (CVS HEAD), it looks to work fine.

Lets get Groovy!
================
Version: 1.0-jsr-04-SNAPSHOT JVM: 1.4.2_07-b05
Type 'exit' to terminate the shell
Type 'help' for command help
Type 'go' to execute the statements

groovy> class B

{ private x }

groovy> b = new B()
groovy> b.x = new Integer(10)
groovy> println b.x
groovy> go
10

private will have no protection in 1.0. private is not inherited, but you can access it
