[CI] XContentParserTests#testSubParserArray fails frequently

[cbuescher]

Just saw three failures in the last few hours:

https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+intake/2818/console
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+artifactory/80/console
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+artifactory/81/console

Reproduces locally with the following seed:

 ./gradlew :libs:x-content:unitTest \
  -Dtests.seed=7F3152E0775C4F75 \
  -Dtests.class=org.elasticsearch.common.xcontent.XContentParserTests \

  -Dtests.security.manager=true \

@henningandersen looks like this was just recently added by you, can you take a look? I will mute the test in the meantime.
