# http4k

[Riku]

Was updating Kotlin, h4k and other deps and noticed h4k seems to have some problems with Kotlin 1.5.20 and core.with. No big deal for me, I am fine at 1.4.32 but I wondered if that issue was on your radar.

Hmmm - that's new to me - can you put a repro together @Riku ?

[Riku]

sure

[Riku]

I did tried to do a repro and everything 👌. So must be something screwy in my project…

[dave]

Obvs I don't know but could it be something with kotlin reflect clashing between 1.4.32 and 1.5.x? Multiple versions of that jar on the CP have caused problems in the past...

[Riku]

yeah I realized while out jogging the same, that kotlin reflect is out of sync and maybe that is it. Must try when I am back at my machine
