OS is Windows XP Home sp3
Version of Commodo Firewall Pro - 3.0.25.378
Was having a problem installing the latest java runtime (1.6.0_06). Installation would get to the 'Applying java patches' and freeze. Java.exe was using 100% cpu according to process explorer. After killing java.exe, the installation completed.
I then opened OpenOffice 2.4, clicked on 'Tools' >> 'Options' and selected the Java option. My system immediately froze. Opened process explorer and found java.exe using 100% cpu. After killing java.exe my system returned to normal. Opened java.exe using cmd prompt and low and behold, java.exe again was using 100% cpu.
Ran every debug program one could think of and after hours of studying the results, noticed that one item was common in all the dumps - guard32.dll.
I then went into System32 and renamed guard32.dll to guard32.dll.bak. Rebooted, opened OpenOffice, clicked on 'Tools' >> 'Options', held my breath and clicked on the 'Java' option. No freeze-up. OO found the path to java.exe and everything working fine.
I then opened java.exe using command prompt and no more 100% cpu usage.
I did a search of this forum and didn't see where the problem I was having with java.exe had been previously posted.
Anyone using OpenOffice 2.4 and having the latest Commodo Firewall version installed should be able to reproduce this problem with java.exe or just open java.exe using command prompt.
BTW I thought maybe the problem had to do with sp3 so I uninstalled it. Same problem after uninstall of sp3.
