Hi community !

Since yesterday we are having issues during Java builds on xenial environment.  
Our TravisCI configuration has not changed since a while.  
We use the openJDK 8 but some unit tests fail with the following error:

```auto
java.lang.IllegalStateException: Could not initialize plugin: interface org.mockito.plugins.MockMaker (alternate: null)
Caused by: java.lang.IllegalStateException: Failed to load interface org.mockito.plugins.MockMaker implementation declared in sun.misc.CompoundEnumeration@6107227e
Caused by: java.lang.IllegalStateException: Failed to load MockMaker implementation: mock-maker-inline
Caused by: java.lang.IllegalStateException: Internal problem occurred, please report it. Mockito is unable to load the default implementation of class that is a part of Mockito distribution. Failed to load interface org.mockito.plugins.MockMaker
Caused by: org.mockito.exceptions.base.MockitoInitializationException: 
Could not initialize inline Byte Buddy mock maker. (This mock maker is not supported on Android.)
Are you running a JRE instead of a JDK? The inline mock maker needs to be run on a JDK.

Is there a change that affects Java builds on Xenial?

The build image provisioning date and time changed between successful and failed builds.  
Latest successful build:

```auto
Build language: java
Build dist: xenial
Build id: 260625977
Job id: 595907204
Runtime kernel version: 4.15.0-1098-gcp
travis-build version: dcbd738d

Below the Travis CI configuration:

```auto

    - "${HOME}/.m2"

jdk:
  - openjdk8

```
