While working on PetitDelphi, we noticed significant performance problems. As PetitDelphi copied the design of PetitJava, we found the same root cause.
When creating a new java parser, a significant amount of time is spend on initialization, especially the creation of parsers for keywords, separators and operators. The introduction of a lexicon cache allows the tests to run significantly faster. 2230 ms to 224ms the second time.

Hi,
I'd like to merge, but right now I'm on vacation and do not have laptop with me. I'll be back on next weekend. Maybe Benjamin Arezki can take a look as he will be working on FAST for Java which also means working with PetitJava.
