/**
 * This class contains copies of the {@link GroovyTokenTypes} constants in static non-final
 * variables. The reason for this is that we must ensure the contants do not get inlined into
 * greclipse bytecode anywhere outside of the org.codehaus.groovy, org.codehaus.groovy16 and
 * org.codehaus.groovy18 bundles.
 * <p>
 * If those constants where inlined, this would create trouble since the values for the constants
 * are generated by the antlr parser generator and they tend to differ between version. This will
 * break things that uses constants inlined from one version while trying to run against another
 * version.
