Java(TM) SE Runtime Environment (build 1.7.0-ea-b01)
Java HotSpot(TM) Server VM (build 20061109103718.sbohne.hs-6444823-fastdebug, mixed mode)
hs_err_pid.log file generated by this Java version has the following vm_info string:
vm_info: Java HotSpot(TM) Server VM (20061109103718.sbohne.hs-6444823) for solaris-sparc, built on Nov 9 2006 11:28:21 by "PRT" with unknown Workshop:0x580
This is ambiguous because the product/fastdebug/debug builds all have the same HOTSPOT_BUILD_VERSION ("20061109103718.sbohne.hs-6444823"). Instead, Abstract_VM_Version::internal_vm_info_string() should use the same string that's returned by Abstract_VM_Version::vm_release().
