Problem summary
**************************************************************** * USERS AFFECTED: IBM BPM Advanced, Standard, and Express * **************************************************************** * PROBLEM DESCRIPTION: You receive the * * ConcurrentModificationException when * * you invoke the TWService.execute(Map * * inputparams) JavaScript API. * **************************************************************** * RECOMMENDATION: * **************************************************************** You receive the ConcurrentModificationException because the input HashMap was being modified. Entries were being added with a new key and removed with the original key while the TWService.execute() API was iterating through its key set.
Problem conclusion
A fix is available that ensures the TWService.execute(Map inputParams) API copies all the objects of the input HashMap, including the objects that the input parameter refers to, which ensures that executing the API is isolated from changes that the application might be making to the objects that were passed into the API. Then the fix iterates through the HashMap, which allows the caller to modify the input HashMap without affecting the execution of the API.
