Hello @merykitty,

I'm observing GHA test failure in `jdk/incubator/vector/ShortMaxVectorTests` on `linux-x86` (jdk master):


test ShortMaxVectorTests.sliceShortMaxVectorTestsMasked(short[-i * 5], short[i + 1], mask[true]): failure
java.lang.AssertionError: arrays differ firstly at element [16]; expected value is <12> but was <1>. (ref: [-135, -140, -145, -150, -155, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27], res: [-135, -140, -145, -150, -155, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]), at index #0, at origin #27

	at ShortMaxVectorTests.sliceShortMaxVectorTestsMasked(ShortMaxVectorTests.java:4812)


Could this be caused by changes in this PR?
