During such reconfiguration we receieve such NPE. I think this is happens because race-condition in OutputStreamAppender thread1 subAppend() - call checkClosed() returns false thread2 LoggerContext.reset() called, that translates to OutputStreamAppender.stop() thread1 call writeBytes - throws NPE, becase appender already closed possible unit test that reproduces NPE {code:java} package ch.qos.logback.core; import java.io.IOException; import java.io.OutputStream; import org.junit.Test; import ch.qos.logback.core.encoder.EncoderBase; public class TestAppender { @Test public void testAppender() throws InterruptedException { OutputStreamAppender<Object> appender = new OutputStreamAppender<Object>() { @Override public void addError(String msg, Throwable ex) { throw new RuntimeException(msg, ex); } }; appender.setEncoder(new EncoderBase<Object>() { @Override public byte[] headerBytes() { return null; } @Override public byte[] encode(Object event) { try { Thread.sleep(1000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } return new byte[] {'A'}; } @Override public byte[] footerBytes() { // TODO Auto-generated method stub return null; } }); appender.setOutputStream(new OutputStream() { @Override public void write(int b) throws IOException { throw new RuntimeException("not closed appender"); } }); appender.start(); Thread t = new Thread(new Runnable() { @Override public void run() { try { Thread.sleep(500); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } appender.stop(); } }); t.start(); appender.doAppend(new Object()); t.join(); } }{code} -- This message was sent by Atlassian JIRA (v7.3.1#73012)
