| DESCRIPTION |
! The following program demonstrates how ORO runs into an endless recursion and thus a stack overflow:--- SNIP ---import org.apache.oro.text.*;import org.apache.oro.text.regex.*;class OROTest { public static void main(String [] args) throws MalformedPatternException { String pat = "'([^'\\\\]+|\\\\?)+'"; PatternCompiler compiler = new Perl5Compiler(); Pattern pattern = compiler.compile(pat); PatternMatcherInput input = new PatternMatcherInput("don't do that"); PatternMatcher matcher = new Perl5Matcher(); matcher.contains(input, pattern); }}--- SNIP ---Best regards, Robert Lichtenberger
