Apache Commons Collections version 3.x is being deprecated from AEMaaCS. The upgraded version 4.4 of Commons Collections is already included as replacement. Customers are advised to upgrade to this version of the library. Please note: the package name was changed to org.apache.commons.collections4. Further note that there are AEM APIs currently exposing the old collections classes; these will be updated in upcoming releases.
Closure implementation that calls another closure n times, like a for loop.

WARNING: from v3.2.2 onwards this class will throw an UnsupportedOperationException when trying to serialize or de-serialize an instance to prevent potential remote code execution exploits.

In order to re-enable serialization support for ForClosure the following system property can be used (via -Dproperty=true):
