This crash is caused by https://bugs.openjdk.java.net/browse/JDK-8261267, when checking whether arch supports the vector operation, it misses the check for op "Op_CallLeafVector". I guess for double 64-bits vector, the vector operation is not supported and should go back to the default java implementation. The missing check make it continue, and the crash happens when making the vector op.
