Issue with compile time enhancement

I have an entity library which I have integrated build time enhancement in.  The enhancer reports it has processed all of my persistent classes.  When I attempt to run a Bootstrap process with this library I get the error shown below.  The entity referenced in the error (Terms) is listed as having been enhanced. I am running with ObjectDB in embedded mode via a reference to a persistence unit also shown below. Please let me know if you need any additional information to diagnose this problem. Thanks, Joel ... ObjectDB Support ObjectDB - Fast Object Database for Java (JPA/JDO) ...

Which one is safer to use? I suppose I should turn on sync="true", right? ... ObjectDB Support ObjectDB - Fast Object Database for Java (JPA/JDO) ...

Hi, We have a query that is constructed dynamically, an example is like this: SELECT DISTINCT $1 FROM CDI $1, Organisation $2, Organisation $3 WHERE ((UPPER($1.cdiId) LIKE 'THREAD14%') AND ((($1.parentOrgId='news') OR (($1.parentOrgId=$2.organisationId) AND ($2.parentOrgId='news'))) OR ((($1.parentOrgId=$3.organisationId) AND ($3.parentOrgId=$2.organisationId)) AND ($2.parentOrgId='news')))) I've also tried running the CDI query first and passing the results into the organisation query as follows: ...

Large query parameter - out of memory

I have an entity object composed of an id, large data in the form of a string and the hashcode of the string as an index. The attached test saves 2000 of these objects, writing the data to a txt file as it goes. It then loops through the data from the file and queries for the entity id based on the data hashcode and the data itself. ... ObjectDB Support ObjectDB - Fast Object Database for Java (JPA/JDO) ...
