Description Viktoras Kovaliovas CLA 2004-02-03 02:32:42 EST 
package test;

public class Test {
	public boolean thru;
}

This code causes Java AST creation failure. After some experiments I came to
conclusion that field name 'thru' is a problem. Problem encountered in M6 and
I20040120 builds.

Comment 1 Jerome Lanneluc CLA 2004-02-03 06:03:57 EST 
Good find! This is indeed a bug in the scanner.
Comment 2 Jerome Lanneluc CLA 2004-02-03 06:59:38 EST 
Fields named 'clons' and 'flals' also make the scanner fail in the same way.
Comment 3 Jerome Lanneluc CLA 2004-02-03 07:28:57 EST 
Fixed Scanner and added regression tests ASTConverter2.test0537a() to test0537c
