Hi Team,

i enable the unit test cases for java agent 1.10.0 version, but there is uncertinity sometime some test pass and some time same test fails.

**Kibana version** :

**Elasticsearch version** :

**APM Server version** :

**APM Agent language and version** : Java agent 1.10.0

**Browser version** :

**Original install method (e.g. download page, yum, deb, from source, etc.) and version**:

**Fresh install or upgraded from other version?**

**Is there anything special in your setup?** For example, are you using the Logstash or Kafka outputs? Are you using a load balancer in front of the APM Servers? Have you changed index pattern, generated custom templates, changed agent configuration etc.

**Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**:

**Steps to reproduce** :  
1.  
2.  
3.

**Errors in browser console (if relevant)**:

**Provide logs and/or server output (if relevant)**:

Yeah, the integration tests are known to be a bit flaky.
