Hi Dandan,

I encountered a build error with our build service:

[  197s] "VfrCompile" -l -n --string-db /home/abuild/rpmbuild/BUILD/ovmf-2018+git1525681922.053cd183c9f2/Build/OvmfX64/DEBUG_GCC5/X64/MdeModulePkg/Library/BootMaintenanceManagerUiLib/BootMaintenanceManagerUiLib/OUTPUT/BootMaintenanceManagerUiLibStrDefs.hpk --output-directory /home/abuild/rpmbuild/BUILD/ovmf-2018+git1525681922.053cd183c9f2/Build/OvmfX64/DEBUG_GCC5/X64/MdeModulePkg/Library/BootMaintenanceManagerUiLib/BootMaintenanceManagerUiLib/DEBUG/. /home/abuild/rpmbuild/BUILD/ovmf-2018+git1525681922.053cd183c9f2/Build/OvmfX64/DEBUG_GCC5/X64/MdeModulePkg/Library/BootMaintenanceManagerUiLib/BootMaintenanceManagerUiLib/OUTPUT/BootMaintenanceManager.i

If I reverted the following change, the package can be built again.

I have no clue now and it happened all the time.

Would you mind to check the code?

Thanks,
