…ines bigger then sizeLimit (#16482) Fixes the behaviour of the tokenizer to be able to work properly when buffer full conditions are met. Updates BufferedTokenizerExt so that can accumulate token fragments coming from different data segments. When a "buffer full" condition is matched, it record this state in a local field so that on next data segment it can consume all the token fragments till the next token delimiter. Updated the accumulation variable from RubyArray containing strings to a StringBuilder which contains the head token, plus the remaining token fragments are stored in the input array. Furthermore it translates the `buftok_spec` tests into JUnit tests. (cherry picked from commit 85493ce)
