Too many non-blocking read actions submitted at once.

How many properties do you have that need to be ignored?

[vivekmore]

In this particular instance there were 9

[filiphr]

Can you please tell me which IntelliJ version are you using?

Can you also reproduce this in standalone project and share the model with us?

I tried with 12 properties and it works without problems in IntelliJ IDEA 2021.1.2 Preview (Ultimate Edition)

[vivekmore]

I don’t think it’s consistently reproducible. I’m using the latest stable version (ultimate 2021.1.1) at the time of this writing. 

[dragove]

It's still buggy with idea 2021.2 and mapstruct-idea 1.3.0
I encountered this exception when I invoked "ignore all unmapped target properties" with 31 unmapped propeties. It should be easy to reproduce with too many unmapped propeties.
