Issue #1840: [ObjectDB 2.6.7_04] Unexpected exception (Error 990)

Type: BugPriority: HighStatus: FixedReplies: 2

Since Version 2.6.7_04 we get the following NullPointerException at Query execution:

[ObjectDB 2.6.7_04] Unexpected exception (Error 990)

Thank you for this report.

The stack trace indicates an unexpected condition at the end of a flush operation (before executing a query).

It doesn't seem related particularly to build 2.6.7_04 or other recent builds, but to issue #1818, that was already fixed. It is unclear why the previous fix is not working, but build 2.6.7_05 includes some addition that maybe can help.

ObjectDB Support
ObjectDB - Fast Object Database for Java (JPA/JDO)

2.6.7_05 works correct.

Thank you for the fix.
