   Pip issue is solved by adding "--user" flag and adding python3-pip. Travis builds are failing now with this issue. 
   
   ```bash
   > Task :swagger-java-client:compileJava
   /home/travis/build/apache/openwhisk/tests/build/swagger-code-java/src/main/java/io/swagger/client/ApiException.java:19: error: package javax.annotation does not exist
   @javax.annotation.Generated(value = "io.swagger.codegen.languages.JavaClientCodegen", date = "2019-10-11T06:14:22.400Z")
                    ^
   ```
   
   Seems like the default version of java is picked as 11. 
   ```bash
   java -Xmx32m -version
   openjdk version "11.0.2" 2019-01-15
   OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
   OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)
   $ javac -J-Xmx32m -version
   javac 11.0.2
   ```
   and it's causing the issue with the swagger doc compilation issue above due to the removal of javax libs. 
   
   Fix - 
   
   1. Added dist as xenial 
   2. Pin JDK version to openjdk8
   3. Added python3-pip package
   
   For future stability, I think we should completely move to python version 3.x as currently, our build, test system is integrated with python2.7 which will be deprecated in Jan 2020.
   
   Please let me know your feedback.
