EJB deployment exception in WildFly 8.2.0

[mjkhan21]

Hello, all.

I'm running into a problem in deploying an EJB jar file.

The jar file contains

• all the class files
• ejb-jar.xml
• jboss-deployment-structure.xml

On deployment, the WildFly app server throws an exception as follows:

"{

    \"JBAS014671: Failed services\" => {\"jboss.deployment.unit.\\\"my-ejb.jar\\\".INSTALL\" => \"org.jboss.msc.service.StartException in service jboss.deployment.unit.\\\"my-ejb.jar\\\".INSTALL: JBAS018733: Failed to process phase INSTALL of deployment \\\"my-ejb.jar\\\"

}"

The Java classes are written and built in Java 8

and the app server is 8.2.0 started also in Java 8.

Any help will be appreciated.

Thanks in advance.

This might do with using JDK8 features where weldclassintrospector doesn't know them that well.

maybe swd847 or jharting might know more.

[jharting]

There should be a full stack trace for the org.jboss.classfilewriter.InvalidBytecodeException exception somewhere in the log. If you can find it and paste it here that would be very helpful.

[mjkhan21]

Hello, guys.

Thanks a lot for the replies.

As requested by Jozef Hartinger, I'm posting the stack trace regarding InvalidBytecodeException below.

I hope this helps.

Thanks again.

[mjkhan21]

I also like to tell you that the EJBs have several lamda expressions and method references here and there.

I hope this helps.

[jharting]

Could you, for the purpose of reproducing the bug, try to simplify the EJB as much as you can to a minimal form that still causes the issue and paste its code here? That would be very helpful.

[mjkhan21]

Hello.

At the request from Jozef Hartinger, I wrote up a simple EJB and deployed it to the WildFly.

After playing with it for a while, I think I found the cause of the InvalidBytecodeException above.

The exception seems to be thrown when an EJB interface contains static default methods.

Following is the initial version of the EJB I wrote to test:

public interface TestManager {

  public static TestManager bean() {return ...// Returns a new instance of the EJB class }

  public static TestManager local() {return ...// Returns a new instance of the local EJB implementation }

  public static TestManager remote(String contextName) {return ...// Returns a new instance of the remote EJB implementation}

  public String greeting(String name);

}

The EJB always failed to be deployed to the WildFly.

However, when I moved the default methods to a class nested inside the interface as below,

the app server had no problem in deploying the EJB.

public interface TestManager {

  public String greeting(String name);

  public static class Factory {

    public static TestManager bean() {return ...// Returns a new instance of the EJB class }

    public static TestManager local() {return ...// Returns a new instance of the local EJB implementation}

    public static TestManager remote(String contextName) {return ...// Returns a new instance of the remote EJB implementation}

  }

}

It seems that whatever object that inspects an ejb deployment has problems with EJBs whose interfaces have (static) default methods.

Hi Emjay,

thanks for isolating trigger of the issue. I filed a bug and sent a fix. You can track progress at https://issues.jboss.org/browse/WFLY-4316
