CodegenException when using TomcatEmbeddedWebappClassLoader (fx. Spring Boot) #42

michaelkrog · 2018-03-01T14:53:32Z

I am having an issue wen running my application with QueryDSL on OpenJDK.

I have 2 classes that I generate QueryDsl classes for. One(Project) is a MongoEntity class that I annotated with @QueryEntity and the other(Service) is a POJO also with @QueryEntity.

I use com.querydsl.apt.QuerydslAnnotationProcessor for generating the classes.

When I compile and run it locally everything works fine. This is using the following JDK:


java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

But when built for production using this JDK:

java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

...and then run in a container with this JDK:

openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-2-b11)
OpenJDK 64-Bit Server VM (build 25.131-b11, mixed mode)

...then I get this exception for the Service class, but not the Project class:

com.mysema.codegen.CodegenException: Compilation of public class Q_2124358794_1275614662_1275614662_1195259493 {

for (dk.codezoo.meerkat.model.Service service : service_) {
    try {
        if (service.getName().toLowerCase().contains(a1)) {
            rv.add(service);
        }
    } catch (NullPointerException npe) { }
}
return rv;    }

}

 failed.

package dk.codezoo.meerkat.model does not exist

Can you check this? Is it only happening with those JDKs?

michaelkrog · 2018-03-01T15:08:20Z

That package does exist. I have tried to unpack the jar just to check it, and it is there.
The two classes are both in the package. One works the other does not.

I just tried to force our build process to update the docker image it uses(openjdk:8-jdk), and that changed the JDK to this:

openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-1~deb9u1-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

But to no avail. It fails with the same exception.

~~But I am only seeing it when I run it on OpenJDK.~~

michaelkrog · 2018-03-01T15:17:19Z

Okay. I just extracted the Jar built for production and ran that locally... And it fails...
So its not only OpenJDK.

Weird. If I built it with maven locally on 1.8.0_121(mac) and run it locally, there is not issue. If built it with 1.8.0_161(linux) and I run that locally, then it fails.

michaelkrog · 2018-03-02T08:00:33Z

I upgraded my mac to JDK 1.8.0_161 and still I am unable to reproduce it when I build i locally.

I then tried to login to our build server(JDK 1.8.0_161 linux), checked out the code, did a fresh build(mvn clean install) and copied the jar-file to my local machine and it fails.

So weird... I'll try to setup a virtual linux locally and reproduce it there.

Shredder121 · 2018-03-02T08:14:17Z

Yes please do, I can't fathom where it would go wrong but can go right in some cases.
So I'd like to hear any progress!

michaelkrog · 2018-03-02T09:03:14Z

I think I found the source of the issue: classpath.

This is the start of the resolved classpath when I run the project via spring-boot:run from intellij:

/Users/michael/Development/meerkat/meerkat/target/classes:/Users/michael/.m2/repository/org/springframework/boot/spring-boot-starter-web/1.5.3.RELEASE/spring-boot-starter-web-1.5.3.RELEASE.jar:/Users/michael/.m2/repository/org/springframework/boot/spring-boot-starter/1.5.3.RELEASE/spring-boot-starter-1.5.3.RELEASE.jar:/...

And this is the start of the classpath when I run the final artifact locally from the commandline (java -jar meerkat.jar):

/Users/michael/Development/meerkat/meerkat/file:/Users/michael/Development/meerkat/meerkat.jar!/BOOT-INF/classes!:/Users/michael/Development/meerkat/meerkat/file:/Users/michael/Development/meerkat/meerkat.jar!/BOOT-INF/lib/spring-boot-starter-web-1.5.3.RELEASE.jar!:/Users/michael/Development/meerkat/meerkat/file:/Users/michael/Development/meerkat/meerkat.jar!/BOOT-INF/lib/spring-boot-starter-1.5.3.RELEASE.jar!:/Users/michael/Development/meerkat/meerkat/file:/Users/michael/Development/meerkat/meerkat.jar!/BOOT-INF/lib/spring-boot-1.5.3.RELEASE.jar!:...

Weird classpath

/Users/michael/Development/meerkat/meerkat/file:/Users/michael/Development/meerkat/meerkat.jar!/BOOT-INF/classes! looks a bit weird, doesn't it?

michaelkrog · 2018-03-02T09:21:15Z

It comes down to

codegen/src/main/java/com/mysema/codegen/SimpleCompiler.java

Lines 71 to 72 in 60b65f9

    
           String decodedPath = URLDecoder.decode(url.getPath(), "UTF-8"); 
        
           paths.add(new File(decodedPath).getAbsolutePath());

The first URL retrieved in my case is jar:file:/Users/michael/Development/meerkat/meerkat.jar!/BOOT-INF/classes!/

At line 71 it is being decoded to file:/Users/michael/Development/meerkat/meerkat.jar!/BOOT-INF/classes!/

At line 72 the absolute path becomes /Users/michael/Development/meerkat/meerkat/file:/Users/michael/Development/meerkat/meerkat.jar!/BOOT-INF/classes!

michaelkrog · 2018-03-06T07:22:18Z

I am unable to make it work.
SimpleCompiler.getClassPath(parent); at https://github.com/querydsl/codegen/blob/master/src/main/java/com/mysema/codegen/JDKEvaluatorFactory.java#L57 returns a classpath that does not work when the application is run as an executable jar built with Spring Boot (https://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-maven-plugin.html).

The classloader is a TomcatEmbeddedWebappClassLoader which resolves jars in the executable jar(Fx. /Users/michael/Development/meerkat/meerkat.jar!/BOOT-INF/lib/spring-boot-starter-tomcat-1.5.3.RELEASE.jar!). But the classpath returned from SimpleCompiler is then broken and classes can then not be resolved.

My knowledge about JavaCompiler and the codegen project is to sparse. I have been unable to create a fix.

Shredder121 · 2018-03-06T07:49:33Z

Yes the issue is known, I'll continue with my fix

Shredder121 · 2018-03-06T07:50:00Z

Thanks for looking into it though, much appreciated!

matteo-gallo-bb · 2018-03-27T15:22:06Z

@Shredder121 I just created a PR to add the support for Codegen to generate code when running in a fat JAR. It should fix this bug and others related to this.
I'm using this fix and it works for me with Spring Boot, Spring Data Key Value, spring-data-hazelcast and QueryDsl Collections.
The PR is: #43
If you can, please review it and let me know if there are possible improvements to do.

michaelkrog · 2018-06-15T10:16:29Z

This issue is indeed fixed by #43.

michaelkrog · 2021-01-21T10:47:47Z

#43 was never accepted even after this many years.

Is there any solution in sight or is building a custom jar still the only viable solution in order to use this with spring boot?

viktorzub · 2021-07-08T11:31:31Z

Any updates here?

viktorzub · 2021-07-12T10:38:58Z

@michaelkrog do you how to build custom jar to make it work on ubuntu/macos?
