  1. /**
  2.  * Adding support for Inform 6 language.
  3.  *
  4.  * Douglas "logicmoo" Miles 02/2014
  5.  * ===================================================================
  6.  * Added support for Java 8 language constructs.
  7.  *
  8.  * Andreas Dangel 01/2014
  9.  * ===================================================================
  10.  * Fix ForStatement to allow Annotations within the initializer.
  11.  *
  12.  * Andreas Dangel 01/2013
  13.  * ===================================================================
  14.  * Fix wrong consumption of modifiers (e.g. "final") in a for-each loop.
  15.  * Check for wrong java usage when catching multiple exceptions.
  16.  *
  17.  * Andreas Dangel 12/2012
  18.  * ===================================================================
  19.  * Enhance grammar to use LocalVariableDeclaration in a for-each loop.
  20.  * This enhances the symbol table to recognize variables declared in such
  21.  * a for-each loop.
  22.  *
  23.  * Andreas Dangel 10/2012
  24.  * ===================================================================
  25.  * Fix parser problem #3530124 with generics
  26.  *
  27.  * Modified the grammar, so that the different usages of generics work.
  28.  * Adjusted the rules, that use "super", as super is no longer a PrimarySuffix.
  29.  * It's now either a ExplicitConstructorInvocation or a PrimaryPrefix.
  30.  * See also test case ParserCornersTest/testParsersCases
  31.  *
  32.  * Andreas Dangel 05/2012
  33.  * ===================================================================
  34.  * Added support for Java 7 language constructs
  35.  *
  36.  * Dinesh Bolkensteyn (SonarSource), 10/2011
  37.  * ===================================================================
  38.  * Changed the CastLookahead production to use 3 lookaheads for primitive types as suggested by Andreas Dangel
  39.  *
  40.  * Brian Remedios 07/2011
  41.  * ===================================================================
  42.  * Added in support for assert as a name using lookaheads
  43.  *
  44.  * Tom Copeland, 09/03
  45.  * ===================================================================
  46.  * Copied over the changes made by Andrea Gini and Marco Savard to
  47.  * support JDK 1.4 language constructs, i.e., asserts.
  48.  * See the java1_4c.jj distributed in the javacc2.1/examples/JavaGrammers directory.
  49.  * Made numerous other modifications to support PMD.
  50.  *
  51.  * Tom Copeland, 6/02
  52.  * ===================================================================
  53.  * This file is a modified version of one originally found in the
  54.  * VTransformer Examples directory of JavaCC1_1. It has been
  55.  * modified to accept Java source code for Java 1.2. Basically,
  56.  * this means a new key word was added, 'strictfp', and that keyword
  57.  * added to the appropriate productions and LOOKAHEADs (where other,
  58.  * similar keywords are listed as possible choices). This involved
  59.  * changing 11 lines.
  60.  *
  61.  * Some other minor changes were made, which can be found by doing
  62.  * a search on 'DW, 7/99'.
  63.  *
  64.  * The goal of this effort was for the grammar to be able to parse
  65.  * any legal Java 1.2 source code. It does not reject all illegal
  66.  * cases, but neither did the original. Plus, when it comes to
  67.  * the new 'strictfp' keyword, the Java Compiler from Sun (JDK1.2.1)
  68.  * also does not reject all illegal cases, as defined by the
  69.  * "Updates" document found at
  70.  *       http://java.sun.com/docs/books/jls/strictfp-changes.pdf
  71.  * (see the testcases.txt file for details).
  72.  *
