Update to JavaCC 8

Reported by: gaben Owned by: team
Priority: normal Milestone: Longterm
Component: Core Version:
Keywords: javacc8 Cc: GerdP

Description

The parser development is moved to version 8, which was released around 2021.

Differences between v8 versus v7: very small at the grammar level, more important at the generated sources level:

  • the JavaCC/JJTree grammar part is the same
  • most of JavaCC/JJTree options should be the same, but some may be removed and others appear in v8
  • the Java grammar part should be nearly the same (may be some Java 7 & Java 8 features will appear in v8 and not in v7); in the future Java 11..17..21.. features would appear only in v8)
  • the C++ / C# grammar parts may be somewhat different
  • some generated files are not much different, others are (the token manager is token driven)

I need to test, but probably newer APIs are already available in the generated code.
