8253563: Change sun.security.jca.Providers.threadLists to be ThreadLocal

[valeriepeng]

Could someone help reviewing this one-line change? This changes the provider list used during jar verification from InheritableThreadLocal to ThreadLocal. Existing usage and handling uses this field as temporary thread-specific provider list for jar verification. There seems to be no reason for it to be InheritableThreadLocal.

Existing regression tests pass with this change.

Thanks,
Valerie
