Activated ObjectDB still throws "Too many persistable types"

I have upgraded from 2.3.7 to 2.4.4 and now my activation won't work, throwing the dreaded com.objectdb.o.UserException: Too many persistable types (>10) - exceeds evaluation limit I have already reactivated and checked that my objectdb.conf is correctly used (by inserting random chars at the beginning of the file, which lead to an error).

Upgrade to 2.4.1_01

Hi, We tried to upgrade from 2.3.7_18 to 2.4.1_01 to pickup some fixes. We discovered that our code no longer works when using 2.4.1_01. We did some probing and found one thing. I have attached the unit test to display this issue. The problem seems to be the annotation at line 266 in the test. In our code for 2.3.7_18, we had @OneToOne(cascade=CascadeType.ALL, fetch=FetchType.EAGER), which is wrong, as Contactdetails is Embeddable, the annotation should be @Embedded. Neither annotation works with 2.4.1_01, with each giving a different error. ... Thank you for this report and for isolating the problem with a test case. Please try build ...
