[8u] RFR: 8185934: keytool shows "Signature algorithm: SHA1withECDSA, -1-bit key"

[Severin Gehwolf]

Hi,

I'd like to backport this simple fix to OpenJDK 8u as it simplifies the
backport of JDK-8172404 to 8u and the patch at hand is low risk. The
JDK 8u patch is the same as the one for JDK 10, except for one context
difference in keytool/Resources.java. The reason for this is that JDK-
8191137 got fixed in JDK 10 *after* JDK-8185934 and in JDK 8u it's the
other way around. Other than that, the patch is identical. Please
review.

webrev: https://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8185934/jdk8/01/webrev/

Thoughts?

Thanks,
Severin
