Show HN: I wrote a Java decompiler in pure C language

The "jikes" compiler from IBM <https://github.com/daveshields/jikespg> was written in C++ and was for the longest time screaming fast. It also had its own parser generator lpg which was fun to play with, if you're into those things <https://github.com/daveshields/jikespg>

It seems someone liked it and made a "v2" along with LSP support https://github.com/A-LPG/LPG2#lpg2

Jikes also gave massively better error messages than the official Java compiler, from what I remember, and it certainly ran a lot faster on the Amiga (https://aminet.net/package/dev/lang/jikes) than trying to run javac via Kaffe (https://en.wikipedia.org/wiki/Kaffe) did.

Certainly not everything on Jikes, given that it was one of the first bootstraped Java toolchains.
