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. PetitJava-DiegoLont.115 Yuriy, can you merge?
