)
Issue Type: Bug Affects Versions: 6.2.2 Assignee: Unassigned Components: hibernate-core
Created: 23/May/2023 07:27 AM Environment: Found using Spring Boot 3.1.0/Hibernate 6.2.2

If an entity has a long (or Long) @Version field
@Version
private long optimisticVersion;
A query like the following:
update versioned Entity set x=true where x=false
will lead to the following Assertion:
ava.lang.AssertionError: null

at org.hibernate.query.sqm.internal.QuerySqmImpl.executeUpdate(QuerySqmImpl.java:705)
Changing the type of the optimisticVersion field to int/Integer allows to workaround the
issue.
I have tracked down the problem to the following code in
BaseSqmToSqlAstConverter.addVersionedAssignment(...) :
value = new BinaryArithmeticExpression(
versionColumn,
ADD,
new QueryLiteral<>( 1, versionType ),
versionType
);
1 is an Integer whereas versionType.getJdbcMapping() is a LongJavaType, explaining why the
assertions fails in the QueryLiteral constructor.
The assertion should probably be relaxed to take into account that an int can be promoted
to a long.
Or alternatively something like in the caller :
versionType.getJavaTypeClass() == Long.class ? new QueryLiteral<>( 1L, versionType )
: new QueryLiteral<>( 1, versionType )
The same issue may happen with other primitive types supporting promotion.
