High memory consumption even after close() of EntityManagerFactory

Hello, we still have memory usage problems. When debugging, we have now observed a case in which the execution of multiple queries increasingly byte array were generated (about 1.5 GB) which from GC could not be released. Not even after the EntityManagerFactory closed. We created a small test with which you can observe similar behavior. The huge memory usage only occurs if we execute the query (line 56 to 61). If we remove this query, all is well. The memory is only released after we re-run a query (on a different database). #1 2015-09-18 09:55 Hello, we still have memory usage problems.

Weird behaviour with enhanced classes and embedded entities

Hi, I've found some weird behaviour in my project (www.tinymediamanager.org): Sometimes some entries of my ArrayLists with embedded entities are missing. I've hunted the problem down to an enhanced/proxied list in my entity which contains embedded entities and some .add(obj) are simply failing. Here is a small sscce which reproduces the issue: #1 2014-07-30 11:27 Hi, I've found some weird behaviour in my project (www.tinymediamanager.org): Sometimes some entries ...

DB Doctor sets type to "unknown" for new fields

Hi, we are using ObjectDB 2.5.4_04 on Linux. We added two new Boolean fields to a persistable type and run DB Doctor on the exiting DB file in order to update the schema. The fields are added to the schema as expected, however their type is set to unknown - we were expecting Boolean. The attached DB file is what was produced by DB Doctor after adding the emergency and broadcast fields. If you run in DB Explorer #1 2014-05-29 03:04 Hi, we are using ObjectDB 2.5.4_04 on Linux.
