JavaCC: You must either use ReInit() or set the JavaCC option STATIC to false

问题

i am using eclipse and JavaCC plugin 1.5.27
i want to use the parser to be executed more than only once. it goes perfect, if using only once. running the parser within the program a second time i get an error:

ERROR: Second call to constructor of static parser.  
       You must either use ReInit() or set the JavaCC option STATIC to false
       during parser generation.

so i add the ReInit() after parsing, but this does not help. this is the code snipped.

  public static void myParser(String toanalyze) throws ParseException
  {
    InputStream is = new ByteArrayInputStream( toanalyze.getBytes() );
    SQLwhereS parser = new SQLwhereS(is);
    .....
    SQLwhereS.one_line();
    .....
    ReInit(is);
  }

looking for all answers from google, but without results. so i am really wondering if i am the only one with this issue.

any help would be great.

kind regards
hans

As I said in my comment, I generally use nonstatic parser. The following "Answer" is more a guess than an authoritative answer. If you try it, please comment, so others (and I) can know whether it's right.

static SQLwhereS parser = null ;

public static void myParser(String toanalyze) throws ParseException
{
    InputStream is = new ByteArrayInputStream( toanalyze.getBytes() );
    if( parser==null) parser = new SQLwhereS(is); else ReInit(is) ;
    .....
    SQLwhereS.one_line();
    .....

}
