java-1.8.0-openjdk/rh1929465-improve_system_FIPS_detection-jdk.patch
Andrew Hughes 3034306917 Detect FIPS using SECMOD_GetSystemFIPSEnabled in the new libsystemconf JDK library. 
Port FIPS system detection support to OpenJDK 8u
Minor code cleanups on FIPS detection patch and check for SECMOD_GetSystemFIPSEnabled in configure.
Remove unneeded Requires on NSS as it will now be dynamically linked and detected by RPM.
