I may not understand your nuance. Which of the following do you mean?
* PL/Java's design is dangerous in terms of the mixture of single- and
multi-threading, and we cannot be 100% sure whether there's really no
problem.
* SPI must not be used in multi-threaded process, even if only one thread
calls SPI functions at a time. So what we can say is that PL/Java is not
safe theoretically in terms of SPI.
