OMG!! - That did the trick!!!!!!
The magic is in persistence.xml
<property name="eclipselink.weaving" value="false"/>
Thank you Geoff you champion!!!!
I wonder what it will do to "performance, caching and change tracking"
because according to that page, that's what weaving is for.

Load average is at 0.7, but I'm monitoring systems during off-peak time.
