[jira] Created: (DIRMINA-348) slf4j InvalidClassChangeError - No
diagnostics
slf4j InvalidClassChangeError - No diagnostics
----------------------------------------------
Key: DIRMINA-348
URL: https://issues.apache.org/jira/browse/DIRMINA-348
Project: MINA
Issue Type: Bug
Components: Core
Affects Versions: 1.0.1
Environment: $ java -version
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-113)
Java HotSpot(TM) Client VM (build 1.5.0_06-68, mixed mode, sharing)
$ uname -a
Darwin gr8.config 8.8.2 Darwin Kernel Version 8.8.2: Thu Sep 28 20:43:26 PDT 2006; root:xnu-792.14.14.obj~1/RELEASE_I386 i386 i386
Reporter: Ben Hood
Priority: Minor
Not having the correct slf4j plugin for the log library you use in a project causes an InvalidClassChangeError.
This manifests itself in the
private void fireEvent( NextFilter nextFilter, IoSession session, EventType type, Object data )
method when the first time the logger instance has a method invoked on it.
The solution is to get the correct plugin on the classpath, e.g. by adding this to your pom:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.2</version>
<scope>runtime</scope>
</dependency>
It would be nice to somehow log this error at least somehow to std err, because the error was being swallowed without any diagnostics being output.
This costs a lot of time and may lead to people not using mina because of a trivial issue.
