Hi, when looking at the jdk9 test results at: http://download.java.net/openjdk/testresults/9/testresults.html it looks like all the transactional memory tests (/hotspot/test/compiler/rtm) passed. However when running them locally, I always get 8 failures (and 30 tests passing). The problem is that the RTM tests are flagged as "Passed" if they run on a machine which does not support transactional memory (because either the CPU or the OS is too old). It would therefore help if you could offer the test result files (i.e. the .jtr files) for every test such that one could see if a test really passed or if it just passed because it was not properly executed. If you can't offer the .jtr files in the near term, could you please let me know if your test machine supports transactional memory? You can easily check this by verifying that the following java command: java -Xlog:os+cpu -version | grep rtm outputs something like: [0.007s][info][os,cpu] flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 fma cx16 xtpr pdcm pcid dca sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm arat epb pln pts dtherm tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 hle avx2 smep bmi2 erms invpcid rtm cqm xsaveopt cqm_llc cqm_occup_llc Thank you and best regards, Volker
