Steffen Offermann commented on LOG4J2-1259:
-------------------------------------------
The test case basically looks like this:
{code}
@Test
public void verifyThatAsyncAppendersAreAvailable()
{
//logTest( Configurator.initialize( "foo", "log4j2-xml-async.xml" ) );
final LoggerContext context = Configurator.initialize( "foo",
"log4j2-xml-async.xml" );
assertThat( context, not( nullValue() ) );
context.start();
context.getLogger( "" ).info( "Test" );
context.stop();
}
{code}
This is the config file:
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn" packages="com.aixigo.tec.logging">
<Appenders>
<Console name="myConsole" target="SYSTEM_OUT" />
<Async name="myConsoleAsync">
<AppenderRef ref="myConsole" />
</Async>
</Appenders>
<Loggers>
<AsyncRoot level="info" />
</Loggers>
</Configuration>
{code}
And this is the error log:
