Java 11 - JAXB is unavailable. Will fallback to SDK implementation which may be less performant

[silver-mx]

When using the plugin with java 11 I can see the following message:

JAXB is unavailable. Will fallback to SDK implementation which may be less performant.

Googling a bit I found the following file from the AWS SDK:

https://github.com/aws/aws-sdk-java/blob/8542b3ddc6be843dc910b3ccb1e6aeb3cc05c001/aws-java-sdk-core/src/main/java/com/amazonaws/util/Base64.java

Which suggests including a dependency to javax.xml.bind:jaxb-api when using Java 9+. Any chance to fix this to make it more compatible with Java 9+?

NOTE: I tried adding the dependency in my build.grade but id did not have any effect apparently.

My bad a runtime dpendency to 'javax.xml.bind:jaxb-api:2.3.1' fixed the issue. Sorry!

[silver-mx]

I am still getting the error I am afraid. Do you have plan to add support for Java 11?

[antgustech]

This issue is still present as of May 2020.

[mdrijwan]

i'm still facing this issue as of January 2021!

[silleruss]

how about add dependency you can find that issue in this wiki

[shaoyongyang]

i'm still facing this issue as of September 2021!

[aniket1418]

I am also facing the same issue in December 2021

Same issue

[AWilson10]

I have the same issue. Message is: WARN [com.amazonaws.util.Base64] - JAXB is unavailable. Will fallback to SDK implementation which may be less performant.If you are using Java 9+, you will need to include javax.xml.bind:jaxb-api as a dependency.

I added this to my pom file but no difference:

javax.xml.bind jaxb-api 2.3.1

[nikitasius]

implementation("javax.xml.bind:jaxb-api:2.3.1") and still facing it.

[schmidlop]

apparently still an issue august 2022

[stephmafole]

In my very last project (August 2022), including JAXB as an implementation dependency solved the issue.

What if you guys give a bit more explanations regarding the logic you're implementing ? It may help definitely solve this issue.

Have the same issue on alpine using jdk-11. Using version 1.12.323 give the same error. Code that causes it: ` AmazonS3 s3Client = AmazonS3ClientBuilder.defaultClient(); TransferManager tm = TransferManagerBuilder.standard().withS3Client(s3Client).build(); PutObjectRequest request = new PutObjectRequest(bucket_name, key_name, new File(file_path));

        Upload upload = tm.upload(request);
        try {
            upload.waitForCompletion();`

I migrated to Spring boot 3 and I no longer have the dependency to javax but instead Jakarta. Is there an update that will solve this ?

@ProLlamaRacer I'm having the same issue, did you find a way around it?

[martppa]

Using latest version solves the issue: implementation 'com.amazonaws:aws-java-sdk-s3:1.12.429' implementation 'javax.xml.bind:jaxb-api:2.4.0-b180830.0359'

FYI I've written some test like below to compare the time, and here is the result with and without the recommended dependencies enabled, and I don't see any difference, moreover the standard java.util.Base64 works the fastest, 9 times (and quite noticeably)

Adding

implementation 'com.amazonaws:aws-java-sdk-s3:1.12.707' implementation 'javax.xml.bind:jaxb-api:2.4.0-b180830.0359'

Solved the issue as of 29 July 2024

[nikitasius]

i use javax.xml.bind:jaxb-api:latest.release & com.amazonaws:aws-java-sdk-s3:latest.release and not seen that for a while.
