Bug 125963 reportContext.getConfigVariableValue() always returns null
The getConfigVariableValue() method of reportContext always returns null. At least it does with the variables I tried, "BIRT_HOME" and "java.version", and "user.name".

	Object getParameterValue( String name );
	/**
	 *

	 * @param value
	 */
	void setParameterValue( String name, Object value );
	/**
	 * 
	 * @param varName
	 * @return
	 */
	Object getConfigVariableValue( String varName );
	/**
