On Jenkins 2.176.2 and credentials-binding-plugin 1.19, the following pipeline will intermittently hang:

pipeline {
    agent any

    stages {
        stage('bug') {
            steps {
                script {
                    for (int i = 0; i < 100; i++) {
                        withEnv(['A=b']) {
                            withCredentials([]) {
                                sh "echo hello ${i}"
                            }
                        }
                    }
                }
            }
        }
    }
}

The build log looks like this:

...
[Pipeline] withEnv
[Pipeline] {
[Pipeline] withCredentials

until the build is aborted.

I've seen two independent things that both seem to work around the problem:

• flipping so `withCredentials([])` wraps `withEnv([...])` seems to avoid the hang.
• ensuring there's always at least one item in the `withCredentials` list parameter seems to avoid the hang.

We run into this in a pipeline where the parameter to withCredentials varies by projects, and sometimes is an empty list.
