Three of our users encountered an ArrayIndexOutOfBoundsException on Windows 10, with JRE 8u102 (64-bit) and 8u111 (32-bit).

The stacktrace is:
java.lang.ArrayIndexOutOfBoundsException: 0
at sun.security.mscapi.KeyStore.engineGetCertificateAlias(KeyStore.java:634)
at sun.security.mscapi.KeyStore$ROOT.engineGetCertificateAlias(KeyStore.java:61)
at java.security.KeyStore.getCertificateAlias(Unknown Source)

KeyStore.getCertificateAlias is not supposed to throw this exception but return null is the supplied argument is not found.

We think this is maybe related to JDK-8139436 / JDK-8148848 but the issue happens with JRE that should include the fix.
