Did you do a reconfigure before building?

common/autoconf/hotspot.m4 lists the potential features that may exist:

# All valid JVM features, regardless of platform
VALID_JVM_FEATURES="compiler1 compiler2 zero shark minimal dtrace jvmti 
jvmci \
     graal fprof vm-structs jni-check services management all-gcs nmt 
cds static-build aot"

so that should exported into the generated build files for use by the 
check-jvm-feature function.
