HTTP PATCH method fails while uploading a file to ADLS Gen2 in jdk 17

Question

We use ADLS Gen2 rest API for uploading and downloading files to ADLS Gen2. To upload a file, we have to invoke PATCH method.

Reference: https://learn.microsoft.com/en-us/rest/api/storageservices/datalakestoragegen2/path/update

We use jersey client to invoke Rest API. By default, Jersey uses HttpUrlConnector and HttpUrlConnector supports only HTTP 1.1 methods, HTTP patch is not supported.
When we try to upload a file in JDK 17, we get the below error :

10.19.2022 00:42:17:514 Thread-13 AzureDakeLakeClient.appendFileInChunks: Error occurred while appending the data datalakefs1/%2Fangular.js directory - Unable to make field private final sun.net.www.protocol.https.DelegateHttpsURLConnection sun.net.www.protocol.https.HttpsURLConnectionImpl.delegate accessible: module java.base does not "opens sun.net.www.protocol.https" to unnamed module @6e732b02

Note: I tested with JDK 15. No issues found.

We tried with Apache Connector with jersey client, but there were issues with content length header.
Could you please suggest a solution for this issue in Java 17.
Also, please let us know if there any plans to replace HTTP PATCH method with PUT.

Answer 1

@Ramya K Firstly, apologies for the delay in responding here and any inconvenience this issue may have caused.

For clients that do not yet support PATCH, you can use PUT with the “x-http-method-override: PATCH” header.

If you have any additional questions or need further clarification, please let me know.
