Re: [eclipselink-users] v. 1.0.2 EntityManagerFactoryImpl throwing null

[Tom Ware <tom.ware@xxxxxxxxxx>]

Hi Gordon,

  If EclipseLink is following the expected code path, the structConverters 
should be initialized inside the "if (state == STATE_PREDEPLOYED) {" code block 
below where the structConverters variable is being defined on the following line:

structConverters = processor.getStructConverters();

  If you are not getting into that if statement and still getting to 
"addStructConverters(session, structConverters)" something strange is occurring 
with your deployment. It is hard to say what the problem is without more 
information about the symptoms of the problem you are seeing.
