Description Johan Compagner 2003-02-06 14:56:59 EST

I will attache a file which does hang my eclipse version (Ibuild 20030205) 
always when i add:

while(st.hasMoreTokens())[cursor-here] and then do CTRL-S (save file)

on the position just after (around line 39):

StringBuffer sb = new StringBuffer();
StringTokenizer st = new StringTokenizer()

it always completely freezes eclipse and eclipse consumes 100% of the cpu.

it also locks up when i don't save the file but press enter after the while() 
and try to type a { on the next row.

This is the thread dump of te freeze with the {
