@mavinkurve thanks for reporting this, which version are you using?

[joel-costigliola]

This is really hard to debug which poor exception information which does not tell what is the duplicated method :(

[mavinkurve]

We started noticing this issue in version 3.9.0. It’s been working perfectly until the upgrade.

[joel-costigliola]

Moving to byte buddy seems to resolve this issue #1093 but this comes with other challenges.

Could be the same issue as https://stackoverflow.com/questions/39670735/classformaterror-duplicate-method-namesignature-from-enhancerbyspringcglib where Rafael Winterhalter says it is a cglib bug.

It could also be related to our shading of cglib, see jdbi/jdbi#26 for a similar issue.

@mavinkurve Which version were you using before upgrading to 3.9.0?

[mavinkurve]

We were using 3.8.0 and I confirmed by downgrading that this issue doesn’t repo there.

The exceptions occurs in AbstractObjectArrayAssert. Sadly a lot of methods have been added to AbstractObjectArrayAssert between 3.8.0 and 3.9.0 :(.

We are moving to byte buddy so this one is going to be fixed.

[mavinkurve]

Thanks everyone.

@joel-costigliola I think that with you merging #1093 this one is resolved.
