For example:

Creating support/modules_libs/java.base/server/libjvm.so from 889 file(s)
/home/shade/trunks/jdk/src/hotspot/cpu/s390/methodHandles_s390.cpp: In static member function 'static void MethodHandles::verify_klass(MacroAssembler*, Register, VMClassID, Register, Register, const char*)':
/home/shade/trunks/jdk/src/hotspot/cpu/s390/methodHandles_s390.cpp:83:32: error: 'VMClassses' has not been declared
   83 | InstanceKlass** klass_addr = VMClassses::klass_addr_at(klass_id);
      | ^~~~~~~~~~
/home/shade/trunks/jdk/src/hotspot/cpu/s390/methodHandles_s390.cpp:84:18: error: 'VMClassses' has not been declared
   84 | Klass* klass = VMClassses::klass_at(klass_id);
      | ^~~~~~~~~~

This is an obvious typo in "VMClassses".
