FIX: Both XSD validation and XSLT transformation fail when you run an SSIS 2014 package that contains multiple concurrent XML tasks

Assume that you deploy a Microsoft SQL Server 2014 Integration Services (SSIS) package to a Microsoft SQL Server 2014 instance. Assume also that the package contains more than one concurrent XML tasks that consume the same XSLT style sheet. When you run the package, you receive the following error message:
[XML Task] Error: An error occurred with the following error message: "The process cannot access the file '<File Path>' because it is being used by another process."

Note This issue also occurs in SQL Server 2012.
The problem was first fixed in the following cumulative update of SQL Server.
