pljava sets the stack_base_ptr for each thread just before it calls into
the backend using SPI and resets it when that thread finishes using SPI.
Only one thread can access the backend at a time, so multi-threaded pljava
code is safe and this mangling of the stack_base_ptr keeps the backend
happy.

Are you having any actual problems or is this all theoretical? I don't
believe you should be having any issues, but if you're having a real
problem, please post a self-contained test case so we can look into it.
