ECDSA SignatureValue do not always have the specified length

A DESCRIPTION OF THE PROBLEM :
This issue has already been reported in JDK-8259535 however, the backport issue was closed for version 1.8 and no backport appears to have been done for 8u372-openjdk (temurin).
There are no links for the pull request. The code in git https://github.com/openjdk/jdk8u/blob/jdk8u372-ga/jdk/src/share/classes/com/sun/org/apache/xml/internal/security/algorithms/implementations/ECDSAUtils.java doesn't have the changes and the test described in the issue still fails.

However, using 8u361-oracle the issue seems to be fixed.
