Stand Alone Validator 1.1.0.0 not Working

[hhund]

Stand Alone Validator throws ClassNotFoundException on startup when validating FHIR resource.

Fixes needed:

• Update Spring Framework spring-core dependency to a newer version that includes ClassFormatException.
• Fix missing ProcessPluginAPI bean.
• Add configuration properties defined in de.netzwerk_universitaetsmedizin.codex.processes.data_transfer.validation.ValidationMain.TestConfig (forwarding proxy, output type / formatting) to Stand Alone Validator documentation.
