The current pattern for Verona based version numbers in this class is limited to tags with 4 digit version numbers. This becomes a problem when a JDK release uses more of the up to 7 possible version digits currently allowed in mainline since [JDK-8207849](https://bugs.openjdk.java.net/browse/JDK-8207849).
