Switch from javaClass look up from static to local

Summary:
For some cases of loading, this function can actually be recursively called. Unfortunately, the static initialization of a local variable in a recursive call is actually undefined behavior and for some compilers this results in a deadlock.

> If the initialization recursively enters the block in which the variable is being initialized, the behavior is undefined.
