- since before that it loops until runEnd is less than or equal to
currentTextEnd:
while (runEnd > currentTextEnd) {
...
}
String str = currentPiece.substring(0, runEnd - currentTextStart);
IMO this is a Tika bug and you should file a bug report (preferrably
with an attached example Word document that causes the issue):
