In Java they're also used for things that are more likely. But although
Java is significantly slower than C++, exceptions are a magnitude faster
than in C++.
That's while with current table-driven exception handling does need to
find the handler for the callers return address. As shared libraries
might be loaded and unloaded asynchronously you've to ask the kernel
for the image of every return address, and that's slow.
