      When I try to run parallel branches with failFast set to false, parallel branch 'foo' kills other parallel branch 'bar' when foo times-out.
      When I use try/catch in 'foo', exception is not being handled and 'bar' gets killed.
      In both cases 'bar is getting killed'

      Code snippet without try/catch:

      pipeline {
    agent any
    options {
        timestamps()
        timeout(time: 30, unit: 'MINUTES')
    }
    stages {
        stage('Setup'){
            steps{
                script{
                    parallel 'foo': {
                        timeout(time: 60, unit: 'SECONDS'){
                            sh "sleep 90"
                        }
                        echo "Done with foo"
                    },
                    'bar': {
                        sh "sleep 200"
                        echo "Done with bar"
                    },
                    failFast: false
                }
            }
        }
    }
}
