Re: [logback-user] Nested Components in appender definition

BinaryIndexedChronicleAppender's setConfig method is using generics (in AbstractChronicleAppender<C>.setConfig(C config)), which is affected by Java's type erasure [1][2][3]. To workaround this, override setConfig with the desired type. public class BinaryIndexedChronicleAppender extends BinaryChronicleAppender<IndexedLogAppenderConfig> { // ... @Override public void setConfig(IndexedLogAppenderConfig config) { super.setConfig(config); } } [1] http://docs.oracle.com/javase/tutorial/java/generics/erasure.html [2] http://docs.oracle.com/javase/tutorial/java/generics/bridgeMethods.html [3] http://codereligion.com/beware-of-java-beans-introspector/
