To be fair to non-Javas, the java version is using Java code because Java sucks at calling out to faster languages.

Oh yes, that Python code looks so idiomatic:

Can't comment on that but why are these people putting spaces after commas (correct) and not to the left and right of the assignment sign = ? It's so weird to read a=b

    regex=PCRE2.pcre2_compile_8(pattern, c_size_t(len(pattern)), c_uint32(0),
   byref(c_int()), byref(c_size_t()), None)

As far as FFI goes, I would say this looks amazingly simple.

That’s very straightforward translation of C code using pcre to Python using ctypes. It doesn’t look great because the ugliness isn’t wrapped in a library. But Python ctypes definitely isn’t hard to use. It is unsafe as hell though.

There's JNI that exists now. And Project Panama will be a big improvement.
