Handle concurrent calls to getModelRegistry

[joaopaulovb]

Just to bring the PR already merged in master to the j11 version. It's possible to create a new release containing this fix?

Hi @ipolevoy, do you have any news about this PR?

[ipolevoy]

@joaopaulovb so sorry, I do not get notifications from Github, and cannot seem to fix this. Just found this PR, are you guys still interested?

Hi, @ipolevoy! We are planning to move to j16 but would be awesome to have this in place until there.

Do you have any plans for java 21?

[ipolevoy]

@joaopaulovb we will release for j11 in the nxt few days, but gearing up to make the last release for java 16, then jump directly to Java 21

@joaopaulovb , the new release has been pushed to Maven Central. It contains this fix. They might take a day-two to propagate across the infrastructure.

The new version of JavaLite is: 3.5-j11
