StubValueStack.findValue(expr,throw) calls itself

The code in 2.2.1 is:

public Object findValue(String expr)

{ return ctx.get(expr); }

public Object findValue(String expr, boolean throwExceptionOnFailure) { return findValue(expr, false); }

I'm pretty sure it ought to be:

public Object findValue(String expr) { return findValue(expr, false); }

public Object findValue(String expr, boolean throwExceptionOnFailure) { return ctx.get(expr); }
