Fix to issue

Hello,
CacheManager#threadCache is a InheritableThreadLocal shared by child thread that sample concurrent downloaded resources.
So underlying Map is shared and can therefore be corrupted.

Put a breakpoint in CacheManager line 177 you will see cache is shared between all Executor threads.
