[eclipselink-users] JPA API compatibility in 1.2/2.0

[Syvalta <syvalta@xxxxxxxxx>]

Hi,

I have succesfully used EclipseLink 2.0-M7 in app server containing JPA1
API. After updating to 2.0-M8 my application no longer deploys. Is 2.0
supposed to work under JPA1 API or should I use 1.1.x (also 1.2 seem to be
JPA2)?

The stack trace if as follows (seems that eclipselink.jar bundles some of
the JPA 2.0 API classes but not spi):
