Change path for urls2.xml file

I am using ObjectDB embedded and have set my home path in relation to the JAR, but running the program still creates .objectdb/urls2.xml in my system user folder.  Is there a setting to change the creation path of this file?  I assumed it would be in relation to the home path, similar to the db and log files. ... <url-history size = "0" user = "true" password = "true" /> The url history is used to enable opening recent ...

I am having a problem in that the in-house library in question reads a simple configuration file to determine available persistence units, and then bootstraps them using the JPA Persistance.createEntityManagerFactory() method and passing in the persistence unit name (again, obtained from the configuration file ). ... > <exclude-unlisted-classes > true </exclude-unlisted-classes > <properties > ... exclude-unlisted-classes to false rather than true .

I have a  entities under many different paths in many different modules, and frequently evolving/changing. JPA2 persistence.xml does not seem to have support for wildcards under the <class> field.

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). ...
