I’ve switched from AdoptOpenJDK to IBM Semeru for my JDK and now I’m getting errors trying to create a Gradle build scan. Here is my `java --version`: ```gradle openjdk 11.0.13 2021-10-19 IBM Semeru Runtime Open Edition 11.0.13.0 (build 11.0.13+8) Eclipse OpenJ9 VM 11.0.13.0 (build openj9-0.29.0, JRE 11 Windows 10 amd64-64-Bit Compressed References 20211022_218 (JIT enabled, AOT enabled) OpenJ9 - e1e72c497 OMR - 299b6a2d2 JCL - 2d83aa3b76 based on jdk-11.0.13+8) ``` And here is the output when I’m trying to create a scan: > **Stack Trace (Click to expand/collapse)** > > ```gradle > BUILD FAILED in 12s > 148 actionable tasks: 148 executed > > A build scan cannot be produced as an error occurred gathering

> [@dyl](#): > > Do you reckon it’s because of Semeru / OpenJ9? It sounds likely, but since the build scan plugin is not open-source, there’s not much the community can say around what specifically might be an incompatibility or if there could be a work-around.
