When configuring the service provider it seems the "oiosaml.servlet.keystore.alias" property value must always be in full lowercase.
In my keystore the alias of the key was shown as "ROV NemLog-in (funktionscertifikat)", but using this value in the configuration resulted in errors suggesting an incorrect keystore password. Changing the property value to full lowercase resolved the problem.
If the alias must be specified in full lowercase, the documentation should state so.
