how to reproduce it:

make test TEST=test/jdk/jdk/incubator/vector/FloatMaxVectorTests.java JTREG="VM_OPTIONS=-XX:MaxVectorSize=8"

here shows a snippet of the error log:

 test FloatMaxVectorTests.powFloatMaxVectorTests(float[-i * 5], float[i * 5]): failure [1ms]
 java.lang.InternalError: not supported: POW Species[float, 2, S_Max_BIT] powf2_u10advsimd
