Could you please provide .jtr files along with the jtreg test results?

Hi Volker,

Finally got the info on the test machine used to run the tests, as you 
expected the machine doesn't
support transactional memory.


This is the output of the command :
[0.011s][info][os,cpu] flags
: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat 
pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt
rdtscp lm 3dnowext 3dnow rep_good extd_apicid pni cx16 lahf_lm 
cmp_legacy svm extapic cr8_legacy
