It is caused by this line in SchemaBuilder:
if (isEmpty(uri)) {
valid =
isEmpty(pSchema.syntacticalTargetNamespace);
} else {
valid =
pSchema.syntacticalTargetNamespace.equals(uri); // <=====
}
Simply inverting the equals will solve the problem
valid =
uri.equals(pSchema.syntacticalTargetNamespace); // <=====
