Is it safe to use a member that is not thread-safe in a bolt or spout?

[姚驰 <ya...@163.com>]

As I ran others' examples, I find that some operations in bolt on members not thread-safe occured with lock like "synchronize" while others not, 
so if I run a bolt with multi-tasks, will the members in it be shared across these threads? Should I make sure that all members are thread-safe?

Hi Yaochi,

Each bolt can have multiple tasks. Each task is represented  by an isolated
instance, their member fields are not shared.
