Error on Oracle LOB handling



    • Type: Bug
    • Status: Open
    • Priority: Major
    • Resolution: Unresolved

      I get the following error

      ORA-24816: Expanded non LONG bind data supplied after actual LONG or LOB column

      on one of our queries.

      The Entity I am trying to write is relatively complicated (includes @Embedded and inheritance), but for legal reasons I am not allowed to disclose the code.

      What seems to happen is, that the not all CLOB columns are updated at the end of the update statement.

      From logs I see:

      databaseProductName: Oracle
      databaseProductVersion: Oracle Database 12c Enterprise Edition Release - 64bit Production
      Using dictionary class "org.apache.openjpa.jdbc.sql.OracleDictionary" (Oracle Oracle Database 12c Enterprise Edition Release - 64bit Production

      I reproduced the bug using all of Oracle driver, and 18.3.

      Unfortunately I cannot downgrade further then version 2.4.0, since our codebase uses Java8 features.

      Hibernate does not show the described behavior, neither does the same code on PostgreSQL.

      I am happy to help debug and fix the issue, but I'd need some guidance (i.e. where to look).

      EDIT: It turns out this issue is very easily reproducible. I created a minimal project doing so at https://github.com/j-be/test-openjpa-2778. No inheritance or @Embedded involved.

      EDIT: Using the test project I can trace it back as far as OpenJPA 2.1.0. 2.0.1 does not seem to be affected, I get a bunch of enhancement exceptions, so not sure whether that is a valid testcase.
