Version

4.1.3

Context

Using DB2, the following query:

select table_name as TABLE_NAME, column_name as COLUMN_NAME,  
             case when data_type = 'CHARACTER VARYING' then 'VARCHAR' else data_type end as TYPE_NAME, 
             null as COLUMN_SIZE, null as DECIMAL_DIGITS, is_nullable as IS_NULLABLE, null as DATA_TYPE 
from sysibm.columns 
where true  and table_catalog = ? 
order by table_catalog, table_schema, table_name, column_name, ordinal_position

throws:

 java.lang.IndexOutOfBoundsException: readerIndex(32741) + length(17) exceeds writerIndex(32757): ReadOnlyByteBuf(ridx: 32741, widx: 32757, cap: 32757/32757, unwrapped: PooledSlicedByteBuf(ridx: 0, widx: 32757, cap: 32757/32757, unwrapped: PooledUnsafeDirectByteBuf(ridx: 32860, widx: 32860, cap: 65536)))

See below for full stacktrace.

Do you have a reproducer?

No, but it should be easy to reproduce by adding the query to an existing test, since it only relies on sysibm.columns (DB2's version of information_schema).

We can provide a reproducer using Hibernate ORM and Reactive PRs. Please let me know if you'd like us to do that.

Steps to reproduce
