I have JBOSS IDE 1.5(eclipse 3.x) on my windows xp computer and it works fine for years. Today when I tried to open JBOSS IDE 1.5, it gives me following error when startup: JVM terminated. Exit code=2

C:\WINDOWS\system32\javaw.exe
-Xmx512m
-jar C:\eclipse\startup.jar
-os win32
-ws win32
-arch x86
-launcher C:\eclipse\eclipse.exe
-name Eclipse
-showsplash 600
-exitdata 1128_70
-vm C:\WINDOWS\system32\javaw.exe
-vmargs
-Xmx512m
-jar C:\eclipse\startup.jar

But I did not change anything for last time good working. So I check javaw.exe on windows/system32 and found it's updated at 2009-07-30.

Really frustrated. How to resolve this problem?
