It is mirrored in org.eclipse.jdt.core.compiler public package where it is API. The mirror implementation is using the backward compatible ITerminalSymbols constant definitions (stable with 2.0), whereas the internal implementation uses TerminalTokens which constant values reflect the latest parser generation state.
