Assert hit on different OS: Windows, Linux, Solaris

Several hs_err files are attached:
1) 1.9.0-ea-fastdebug-b84, Linux / Oracle Linux 6.3, x86_64: hs_err_pid19558.log
2) 1.9.0-ea-fastdebug-b84, Win32 / Windows Server 2012 R2 Standard: hs_err_pid2308.log
3) 1.9.0-ea-fastdebug-b82, Solaris / Solaris 11, i86pc: hs_err_pid5977.log

Probably, can be the same issue as in JDK-8067154
