Character type properties are not converted properly by the EDBUtils class.
Specifically the transformation from a JPAEntry to a EDBObjectEntry.
Character is handled by the DefaultConverterStep, which assumes all primitive classes have a "valueOf(String)" method or a Constructor with a String argument. However Character does not have any of those.
To solve this, either a new ConverterStep needs to be introduced, or the DefaultConverterStep.getEntryValue(JPAEntry) method needs to be changed.
