While SIP requires sub-second precision, it does not require millisecond 
precision.  :-)

In any case, garbage collection is definitely a problem, but there are 
ways of optimising the JVM's GC behaviour to be more or less favourable 
to the task.

That is definitely true, though one might argue that this is a cultural 
problem rather than an innate Java problem.

In any case, I am not a Java programmer and am not defending Java, so 
please don't misconstrue my stance.  I'm just saying that it might not 
be _wholly_ unsuitable to the task.

I do not think, and have never thought, that Java is an ideal language 
in which to implement SIP call processing.
