Description
In java/awt/font/TextJustifier.java justify there is a potential code path where divison by zero might happen , see also the Sonar finding :
https://sonarcloud.io/project/issues?id=shipilev_jdk&open=AXcqMwpm8sPJZZzONu1k&resolved=false&severities=CRITICAL&types=BUG
boolean hitLimit = (weight == 0) || (!lastPass && ((delta < 0) == (delta < gslimit)));
boolean absorbing = hitLimit && absorbweight > 0;
// predivide delta by weight
float weightedDelta = delta / weight; // not used if weight == 0
In case of (weight == 0) the division should not be done because the value of weightedDelta is unused in this case anyway.
