MOHD commented on FOP-2341:
---------------------------

Looks like issue with font-size. Due to that code are going in infinite loop.
Find below code where infinite loop.occur.
File Name: FontSizePropertyMaker.java


 while (scale < 1 && nextStepFontSize > baseFontSize
                || scale > 1 && nextStepFontSize < baseFontSize) {
            // baseFontSize is still bigger (if we grow) or smaller (if we 
shrink)
            // than the last caculated step
            lastStepFontSize = nextStepFontSize;
            nextStepFontSize = (int)Math.round(lastStepFontSize * scale);
        }

Test scenario: 

 <fo:block font-style="normal" font-size="10mmpt">
      <fo:block font-size="larger" font-style="normal">
       Text  </fo:block>
 </fo:block>
