I've found that by modifying a small block of code, I can solve this problem:

final String name = String.format(
	"BasicType adapter for AttributeConverter<%s,%s>",
	entityAttributeJavaType.getSimpleName(),
	databaseColumnJavaType.getSimpleName()
);

modified to this:

final String name = entityAttributeJavaType.getCanonicalName();

I've used the latest version 4.3.7-SNAPSHOT from git and all tests passed.
I'll come back with confirmation after some more in development tests.
