Re: [eclipselink-users] NullPointerException in QuerySequence.java line

[Andrei Ilitchev <andrei.ilitchev@xxxxxxxxxx>]

I don't have Informix db, so I set InformixPltform to be used with 
Oracle db - and could not reproduce the problem:
an object using TableGenerator was persisted.

The query == null is indication that the sequence hasn't been 
initialized (see TableSequence.onConnect method). That happens during 
descriptor initialization, right after the session is connected.
