1126 Cannot conditionally change volatility from frozen if class is currently open
Cause
This error occurs when you use the changeObjectVolatility method of the Object class to change the volatility of a frozen object. If the condition parameter is set to true, situations can be detected where it is not safe to allow the change.
Action
Ensure that no other applications are holding the class open when attempting to change the volatility of a frozen instance of that class.
