reactor / BlockHound

I believe the packaged native library name for Windows is incorrect. The call System.mapLibraryName("BlockHound") resolves to BlockHound.dll on Windows, while the library is packaged as libBlockHound.dll.

I tested against latest Build-Snapshot from 22-Feb-2019 14:43 on Java 8. Thank you.

Hi @jrehwaldt,

Thanks for trying it on Windows! Unfortunately, I haven't had a chance to test it on Windows, and your report is very valuable!

It should be as simple as changing this line:

BlockHound/agent/build.gradle

Line 19 in e98e2db

    
           from "${rootProject.project(":native-agent").buildDir}/external-build/BlockHound/windows/libBlockHound.dll"

Would you like to take a chance to contribute? :)

Sure, I'll give it a try.

Released in 1.0.0.M2 🎉
