auto-generated uuid fields

Hello, we're porting a JDO application to ObjectDB which uses uuid-hex generated values. However the page on generated values in your JPA tutorial only mentions numeric generated values, and when we try to use it the error message seems to imply that auto-generating strings isn't supported. Could you confirm whether this is the case? If so it seems an odd omission, given that it's part of both the JPA and JDO standards (JPA Generator.UUID_HEX and JDO value-strategy="uuid-hex") and that the Java language itself supports it (java.util.UUID).

Performance problem

Hi, we have a strange performance problem with ObjectDB 2.5.3_01 and JBoss 7.1.1. We have two ObjectDB databases on one ObjectDB server. Production database is running 5-10 times slower than test database. Their size and number of records are almost identical. When running production database in separate test environment its speed is very good. We did a performance analysis on our 2 linux servers one running JBOSS and other running ObjectDB. - CPU utilization of JBOSS server is max 5-10% (per core)... problem as a schema change problem but will try again to fix it. regards.
