Jenkins unexpected exception java.nio.channels.ClosedByInterruptException when deleting a big folder from Artifactory - jenkins

Question

In my Jenkins shared lib, I’ve created a class called ArtifactManager which performs docker cleanup from Artifactory when branch is deleted.
When there is a really massive directory of docker images to delete (~50 GB), I’m getting an unexpected interrupt:

My code is not included in the stack trace…
The code which performs the HTTP requests is:
def deleteArtifact(String pathOnServer){
def responseCode, data
Boolean deleted = true
Logger.printInfo(steps, "Deleting $server/$pathOnServer artifact from server")
steps.withCredentials([steps.usernamePassword(credentialsId: 'artifactory_user', passwordVariable: 'PASSWORD', usernameVariable: 'USERNAME')]){
(responseCode, data) = sendApiRequest("$server/$pathOnServer", "DELETE")
}
//if !2xxSuccessful() -> Http response codes family - 1xx: Informational, 2xx: Success, 3xx: Redirection, 4xx: Client Error, 5xx: Server Error
if((responseCode / 100 as int) != 2){
deleted = false
Logger.printError(steps, "Failed to delete: `$pathOnServer` from `$server`. Status Code: $responseCode")
Logger.printError(steps, "Data: $data")
}
return deleted
}
def sendApiRequest(String query, String httpMethod, String contentType ="", String data =""){
def responseCode
def responseData
def conn = new URL("${this.protocol}://$query").openConnection()
//Trying to increase timeout
conn.setConnectTimeout(15 * 60 *60 * 1000);
conn.setReadTimeout(15 * 60 *60 * 1000);
def auth = "${steps.env.USERNAME}:${steps.env.PASSWORD}".getBytes().encodeBase64().toString()
conn.setRequestProperty("Authorization", "Basic ${auth}")
conn.setRequestMethod(httpMethod)
if(contentType) conn.setRequestProperty( "Content-Type", contentType);
if(data){
conn.setDoOutput(true)
conn.getOutputStream().write(data.getBytes("UTF-8"));
//Note: the POST will start when you try to read a value from the HttpURLConnection, such as responseCode, inputStream.text, or getHeaderField('...'). (https://stackoverflow.com/a/47489805/10025322)
}
responseCode = conn.getResponseCode()
try{
responseData = conn.getInputStream().getText()
}catch(IOException e){
responseData = e.getMessage()
}
conn = null
return [responseCode, responseData]
}
I also tried to use a different library for performing the request but still getting the exception when Artifactory responses slowly (Delete huge directory):
def sendApiRequest(String query, String httpMethod, String contentType ="", String data =""){
def responseCode
def responseData
def http = new HTTPBuilder("${this.protocol}://$query")
http.request(Method.valueOf(httpMethod)) {
headers.'Authorization' = "Basic ${steps.env.USERNAME}:${steps.env.PASSWORD}".getBytes().encodeBase64().toString()
if (contentType) {
headers.'Content-Type' = contentType
requestContentType = contentType
}
if (data) {
body = data
}
response.success = { resp, reader ->
responseCode = resp.statusLine.statusCode
responseData = reader.text
}
response.failure = { resp, reader ->
responseCode = resp.statusLine.statusCode
responseData = reader.text
}
}
echo("RESPONSE_CODE: " + responseCode.toString() + " RESPONSE_DATA: " + responseData.toString())
return [responseCode, responseData]
}
I found that the ClosedByInterruptException may occur due to the following reasons:
The thread running the code was interrupted.
The connection to the remote server was closed due to a network error.
The server explicitly closed the connection.
The read/write operation timed out.
There was an interruption or failure in the underlying I/O operations.
The JVM was shut down while the operation was in progress.
Any idea how to handle/workaround?

The provided code doesn't work due to a bug in Jenkins' core (this issue was marked as fixed in jenkins >= 2.332.1LTS or 2.335)
As a workaround you can use:
def sendApiRequest(String query, String httpMethod, String contentType ="", String data =""){
/*
Caller must wrap function call with 'withCredentials' statement
with 'USERNAME' and 'PASSWORD' environment varaiables
*/
String apiCmd = """curl -s -w '###%{http_code}' -X '${httpMethod}' \
'${this.protocol}://$query' \
${contentType ? "-H 'Content-Type: $contentType'" : ''} \
-u "\$USERNAME:\$PASSWORD" \
${data ? "-d '${data}'" : ''}"""
def response = steps.sh(returnStdout: true, script: apiCmd, label: "Send API request to Artifactory").trim()
def responseCode = response.split("###")[1]
def responseData = response.split("###")[0]
try{
responseCode = responseCode.toInteger()
} catch (NumberFormatException e) {
throw new RuntimeException("Invalid status code: `$responseCode` cannot cast to integer")
}
return [responseCode, responseData]
}
