=0AGreetings,=0A=0AI was trying to debug oscar code running on kaffe.=0A=0A=
I found,  variable startLevel is always zero (which is a not expected) as i=
n shutdown routine startlevel is set 0 to stop bundles.=0A=0AIn Oscar.java/=
setStartLevelInternal() routine  just before =0A=0A                  startB=
undleForStartLevel(impl); //line number 724=0A=0Ai inserted =0A            =
      setStartLevelInternal(1); =0A=0Ato set startlevel to 1.=0A=0AWith thi=
s modification it is not giving me DEADLOCK error( i don't know why startle=
vel was always zero)=0A=0ABut now it is giving me stackOverFlowError.=0A=0A=
I tried to increase stack size with =0A=0A           java -jar -ss 64M lib/=
oscar.jar=0A=0Abut then is gives me OutOfMemoryError. =0A=0AI tried with =
=0A=0A          java -jar -ss 64M -ms32M -mx 256[512]M  lib/oscar.jar=0A=0A=
but again same OutOfMemoryError.=0A=0AMay be i should look forward to upgra=
de my system, but i just wanted to give feedback on startLevel problem.=0A=
=0AAny Suggestions ? =0A=0AThanks & Regards,=0AGaurav Ganeriwal =0A=0A=0AOn=
