Message : TJBench: Remove innocuous always-true condition This was accidentally introduced into tjbench.c in 890f1e0413b54c40b663208779d4ea9dae20eaef and ported into the Java version from there. Based on https://github.com/libjpeg-turbo/libjpeg-turbo/pull/571/commits/4be6d4e7bdd09a73ee8456aa07693afa31ef2148 Refer to #571
