It seems that the double semicolon in the `Instant` class member in `DefaultRevisionMetadataUnitTests` is a typo.

## DefaultRevisionMetadataUnitTests.java
```java
class DefaultRevisionMetadataUnitTests {

	private static final Instant NOW = Instant.now();;
```

I was reading the test code and found these codes.
I think having 2 semicolons is a typo, so wouldn't it be okay to remove them?
