Hi @bsideup
I created a project to reproduce this issue: https://github.com/sergey-morenets/blockhound
If I run SampleReactor or SampleWebFlux in IDE (for example, Intellij Idea 2019.2) I get this exception.
from blockhound.
If I use JDK 1.8.0.191 or remove reactor-tools dependency the exception still appears.

Hi @sergey-morenets,
I just tried to run Spring Boot 2.2.1 with BlockHound 1.0.1 on JDK 11 and it did not fail.
Could you please provide a reproducer maybe?
from blockhound.
Hi @bsideup
Yes, I will try to narrow down this issue and provide a project to reproduce it.
from blockhound.
@sergey-morenets
Thanks! I confirm the bug. I need to check whether the bug comes from ByteBuddy or not. Meanwhile, please add this dependency as a workaround:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.29</version>
</dependency>
from blockhound.
Looks like a bug in ByteBuddy, reported:
raphw/byte-buddy#780
from blockhound.
@sergey-morenets do you also see that the blocking calls are not reported or it is just the annoying error log statement?
I did some testing and it seems that, despite the error message, the instrumentation works fine and the calls are reported as usual.
from blockhound.
Hi @bsideup
Since my application terminated because of exception I didn't check whether actual instrumentation worked as expected.
from blockhound.
closing this since the associated ByteBuddy issue has been resolved on top of original workaround
from blockhound.
