Using hyphenate="true" rendering text within a too small area (e.g. a small 
table column) results in an inifite loop. The loop appeares in FOText.java 
line 280 ("while ( start != -1)") which never ends, because 
LineAread.addText(...) never returns -1. I think The bug should be fixed in 
LineAread.addText(...). Example document:
