Remarks

If the specified key is not already associated with a value or is associated with null, associates it with the given value. Otherwise, replaces the value with the results of the given remapping function, or removes if the result is null. This method may be of use when combining multiple mapped values for a key.

If a security manager is enabled, its checkSecurityAccess method is called with the strings "putProviderProperty."+name and "removeProviderProperty."+name, where name is the provider name, to see if it's ok to set this provider's property values and remove this provider's properties.
