Android 7.x 8.x Buid Failed with OpenJDK

[Xiang Li]

Hi Android Team,

I build Android 8.1 on Ubuntu 18.04 failed recently when openjdk-8 updated to 1.8.0_292

as the jack-server communition failed.

Error message is:

FAILED: setup-jack-server
/bin/bash -c "(prebuilts/sdk/tools/jack-admin install-server prebuilts/sdk/tools/jack-launcher.jar prebuilts/sdk/tools/jack-server-4.11.ALPHA.jar 2>&1 || (exit 0) ) && (JACK_SERVER_VM_ARGUMENTS=\"-Dfile.encoding=UTF-8 -XX:+TieredCompilation\" prebuilts/sdk/tools/jack-admin start-server 2>&1 || exit 0 ) && (prebuilts/sdk/tools/jack-admin update server prebuilts/sdk/tools/jack-server-4.11.ALPHA.jar 4.11.ALPHA 2>&1 || exit 0 ) && (prebuilts/sdk/tools/jack-admin update jack prebuilts/sdk/tools/jacks/jack-4.32.CANDIDATE.jar 4.32.CANDIDATE || exit 47 )"
Jack server already installed in "/home/lixiang/.jack-server"
Communication error with Jack server (35), try 'jack-diagnose' or see Jack server log
SSL error when connecting to the Jack server. Try 'jack-diagnose'
SSL error when connecting to the Jack server. Try 'jack-diagnose'

And the reason seems related OpenJDK version, as when I install older version of JDK, the build process is OK.

faild java -version:

openjdk version "1.8.0_292"

OpenJDK Runtime Environment (build 1.8.0_292-8u292-b10-0ubuntu1~18.04-b10)

OpenJDK 64-Bit Server VM (build 25.292-b10, mixed mode)

successed java -version:

openjdk version "1.8.0_41"

OpenJDK Runtime Environment (build 1.8.0_41-b04)

OpenJDK 64-Bit Server VM (build 25.40-b25, mixed mode)

When I read the release Notes of 1.8.0.291 I found that SSL algo is limited by security policy.

https://java.com/en/download/help/release_changes.html

• Other notes: Disable TLS 1.0 and 1.1
  TLS 1.0 and 1.1 are versions of the TLS protocol that are no longer considered secure and have been superseded by more secure and modern versions (TLS 1.2 and 1.3).
  These versions have now been disabled by default. If you encounter issues, you can, at your own risk, re-enable the versions by removing "TLSv1" and/or "TLSv1.1" from the jdk.tls.disabledAlgorithms security property in the java.security configuration file.
  See JDK-8202343

And I change the policy file, building is fine with version 292.

/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/java.security
->     jdk.tls.disabledAlgorithms = SSLv3

So problem is solved for me but changing JDK property file is not a good way to solve this issue.

Is there a way to update jack-server to adapt to latest JDK version?

or could I get a copy of jack-server souce?

Thanks and Regards.
