I enabled SQLtrace and the SQL generated for OPENJPASAMPLE.D is missing fields from its relation to VC. I am expecting create table D command to be
CREATE TABLE OPENJPASAMPLE.D (id INTEGER NOT NULL, VC_VCID INTEGER, VC_VCS_VCSID INTEGER, VC_VCS_E_EID INTEGER, C_CID INTEGER, C_CM_CMID INTEGER, C_CM_E_EID INTEGER, PRIMARY KEY (id,VC_VCID INTEGER, VC_VCS_VCSID INTEGER, VC_VCS_E_EID INTEGER))

So I am assuming that it is failing at generation of foreign key command for OPENJPASAMPLE.D table.
When the classes C and CM are renamed to WC and WCM (i.e alphabetically higher than VC and VCS) the problem goes away.
