A DESCRIPTION OF THE PROBLEM :
Trying to render html code inside a JEditorPane, I get NumberFormatException due to not clean code in rows attribute of frameset:
<frameset rows= " 120px,* " frameborder= " 0 " border= " 0 " framespacing= " 0 " >
<frame src= " / " scrolling= " auto " name= " entete " >
<frame src= " / " scrolling= " auto " name= " detail " >
</frameset>

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run code. As you can see frame contains:
rows= " 120px,* "
which should be:
rows= " 120,* "

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The HTML is rendered
ACTUAL -
