> Key: DELTASPIKE-1333
> URL: https://issues.apache.org/jira/browse/DELTASPIKE-1333
> Project: DeltaSpike
> Issue Type: Improvement
> Components: Configuration
> Affects Versions: 1.8.1
> Environment: Java 8, DeltaSpike 1.8.1
> Reporter: Niels Ull Harremoes
> Assignee: Mark Struberg
> Priority: Minor
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> I wanted to implement a default method in one of my configuration methods as
> a simple way to configure a Duration:
> {code:java}
> @Configuration
> interface CacheConfig {
> @ConfigProperty(name = "cache.lifetime", defaultValue = "P1D")
> String cacheLifetime();
> default Duration getCacheLifetimeDuration() {
> try {
> return Duration.parse(cacheLifetime());
> } catch (DateTimeParseException e) {
> ...
> }
> }
> {code}
> However, a runtime I get the error
> {quote}java.lang.UnsupportedOperationException: public default
> java.time.Duration com.example.CacheConfig.getLifetimeDuration() doesn't have
> @ConfigProperty and therefore is illegal
> {quote}
> It would be nice if default methods were not processed.
