All the above listed builds are failing with "Unsupported major.minor
version 52.0" error.

[ZooKeeper_branch35_jdk7] $ /home/jenkins/tools/ant/latest/bin/ant
-Dtest.output=yes -Dtest.junit.threads=8 -Dtest.junit.output.format=xml
-Djavac.target=1.7 clean test-core-java
Exception in thread "main" java.lang.UnsupportedClassVersionError:
org/apache/tools/ant/launch/Launcher : Unsupported major.minor version 52.0
at java.lang.ClassLoader.defineClass1(Native Method)

As per the jira https://issues.apache.org/jira/browse/INFRA-13526
discussion, it needs to change the build configuration. Could you please
help to do the necessary conf changes. Thanks!


Rakesh
