Tobias Gierke commented on WICKET-6552:
---------------------------------------
I did some further experiments but I'm unable to get a proper stack trace (with
line numbers for ClassReader) with neither IntelliJ nor Eclipse (I even
re-downloaded the ASM sources.jar from Maven central manually..for some reason
the class files do not seem to match the sources as also breakpoints wouldn't
work there in both Eclipse and IntelliJ).
Anyway, I also got occasional IAEs with cglib 3.1 and ASM 5.0.3 so seems
there's something I'm missing ... I now upgraded to cglib 3.2.6 and ASM 6.1.1
and no exceptions so far....

> Key: WICKET-6552
> URL: https://issues.apache.org/jira/browse/WICKET-6552
> Project: Wicket
> Issue Type: Bug
> Components: wicket-spring
> Affects Versions: 8.0.0
> Environment: Ubuntu 18.04 LTS , 64-bit
> Oracle JDK 10.0.1
> Reporter: Tobias Gierke
> Priority: Major
>
> Seeing that Wicket 8 just got released I was eager to try out the goodies but
> got stopped quickly by an IAE on some (but not all) web pages inside
> cglib/asm (see below for the stacktrace).
> Inside WEB-INF/lib we've got:
> asm-5.2.jar
> asm-tree-5.2.jar
> asm-util-5.2.jar
> cglib-3.2.5.jar
> which is what I would expect looking at the pom.xml for wicket-ioc 8.0.0 so
> IMHO the classpath is correct. Everything works fine with wicket-ioc 7.10 and
> JDK 10.0.1 which was using:
>
> asm-5.0.3.jar
> asm-tree-5.0.3.jar
> asm-util-5.0.3.jar
> cglib-3.1.jar
>
> Overriding the dependencies like this:
>
> <dependency>
> <groupId>cglib</groupId>
> <artifactId>cglib</artifactId>
> <version>3.1</version>
> </dependency>
>
> <dependency>
> <groupId>org.ow2.asm</groupId>
> <artifactId>asm-util</artifactId>
> <version>5.0.3</version>
> </dependency>
>
> makes the exception go away.
> I had a brief look at the ClassReader constructor and it seems the IAE gets
> thrown because of a classfile version not supported by ASM ... funny thing
> is, ASM 5.0.3 is way older than 5.2 and doesn't crash so it's likely that the
> generated bytecode passed to this method somehow has a different (older)
> classfile version..
