[Pipeline] Start of Pipeline
expected to call org.kohsuke.groovy.sandbox.impl.SandboxedMethodClosure.call but wound up catching WorkflowScript.hello; see: https://jenkins.io/redirect/pipeline-cps-method-mismatches/
[Pipeline] echo
hello
[Pipeline] End of Pipeline
Finished: SUCCESS
As evidenced by the "hello" output, the hello method runs normally, so the warning is a false positive.
We came across the exact same warning when calling a method via a pointer. The method is called correctly and works fine, apparently this is a false positive warning.
