Maven project with example JPQL in entity
It appears that under some conditions JPQL is not parsed and no code completion hints are available.
Please see in the attached example, CustomerOrder.java
The remaining files in the project are not relevant.
Perhaps the condition that is relevant here has other effects, too. I notice that since JPQL parsing was addded, the IDE is much slower but that might be a coincidence.
I would still prefer that JPQL support becomes an optional module.
