I get SolrParser.kt:9:9 Class '<anonymous>' is not abstract and does not implement abstract member 'containsKey' when extending a java class anonymously in K2. This works fine in 1.9.x. Any ideas how to fix this?

Local object:

object SolrParser {
    @JvmStatic
    fun asInputDoc(keysAndValues: Map<String, Any?>): SolrInputDocument =
        object : SolrInputDocument() {
            init {
                keysAndValues.forEach { (key, value) -> addField(key, value) }
            }
        }

From solr-solrj-9.6.0.jar:

public class SolrInputDocument extends SolrDocumentBase<SolrInputField, SolrInputDocument>
    implements Iterable<SolrInputField> {
  ...

  @Override
  public boolean containsKey(Object key) {
    return _fields.containsKey(key);
  }

Hi. ~Could you please report this issue to kotl.in/issue?~

The workaround is to explicitly override reported functions
I checked, this compiles fine:

object SolrParser {
    @JvmStatic
    fun asInputDoc(keysAndValues: Map<String, Any?>): SolrInputDocument =
        object : SolrInputDocument() {
            init {
                keysAndValues.forEach { (key, value) -> addField(key, value) }
            }

            override fun containsKey(key: String?): Boolean {
                return super.containsKey(key)
            }

            override fun get(key: String?): SolrInputField? {
                return super.get(key)
            }

            override fun remove(key: String?): SolrInputField? {
                return super.remove(key)
            }
        }
}

Thanks! Hope this'll be sorted in the next version 🙂
