Had same problem, after looking at source code can say, that IndexOutOfBoundsException happens when you try to rerun your application and first action (in my case) is trying to view audit change detail.

Want you to notice, that in this case in javers/javers-persistence-sql/src/main/java/org/javers/repository/sql/repositories/GlobalIdRepository.java in this method:

    public Optional<Long> findGlobalIdPk(GlobalId globalId) {
        if (disableCache){
            return findGlobalIdPkInDB(globalId);
        }

        Long foundPk = globalIdPkCache.getIfPresent(globalId);

        if (foundPk != null){
            return Optional.of(foundPk);
        }

        Optional<Long> fresh = findGlobalIdPkInDB(globalId);
        if (fresh.isPresent()){
            globalIdPkCache.put(globalId, fresh.get());
        }

        return fresh;
    }

Instead of taking value from cache it goes to findGlobalIdPkInDB(globalId) method as you can see. So, basically, to recreate this bug you must trigger this method.

So the problem is in jsonConverter.toJson(((InstanceId)globalId).getCdoId()) in this section of findGlobalIdPkInDB(globalId) method (don’t know about other cases).

//...
 else if (globalId instanceof InstanceId){
            query
                .where(GLOBAL_ID_LOCAL_ID + " = :localId ")
                .withArgument("localId", jsonConverter.toJson(((InstanceId)globalId).getCdoId()))
                .append("AND " + GLOBAL_ID_TYPE_NAME + " = :qualifiedName ")
                .withArgument("qualifiedName", globalId.getTypeName());
        }
//...

Argument localId is becomes like, for example, ""1111"" instead of "1111" so querying DB returns nothing. I think that jsonConverter.toJson(((InstanceId)globalId).getCdoId()) causes it and it must be replaced with just globalId.getCdoId() to prevent problem so it looks like this:

//...
query
    .where(GLOBAL_ID_LOCAL_ID + " = :localId ")
    .withArgument("localId", globalId.getCdoId())
    .append("AND " + GLOBAL_ID_TYPE_NAME + " = :qualifiedName ")
    .withArgument("qualifiedName", globalId.getTypeName());
//...

I am using PostgreSQL DB, if it might help to resolve this problem.

This issue is the same with issue I just report few minutes ago (https://github.com/javers/javers/issues/685) Your test case alway pass because before you already call javers.commit() before, and it stored in cache.

To reproduce this issue, you can try with some step as below

1. Create new Springboot project and integrate it ith Javers
2. Start project and insert/update some information
3. Stop server and start again (The reason is I want to clean cache)
4. Call finsSnapshot with InstanceId
