XmlValidationModeDetector: length of a string is always greater than index of any of its characters [SPR-11477]

[spring-projects-issues]

Rajeev Bahuguna opened SPR-11477 and commented

The method org.springframework.util.xml.XmlValidationModeDetector::hasOpeningTag should have this:
return (openTagIndex > -1 && content.length() > (openTagIndex+1) && Character.isLetter(content.charAt(openTagIndex + 1)));

in place of the current:
return (openTagIndex > -1 && content.length() > openTagIndex && Character.isLetter(content.charAt(openTagIndex + 1)));
