synthetic source
URL: https://github.com/apache/beam/pull/7226#issuecomment-451454972
I think I've found the source of the problem - I didn't look to "stacktrace"
tab in logs before. I get the following error after rebasing this branch to
master:
```
java.lang.NoSuchMethodError:

This started happening after https://github.com/apache/beam/pull/7324 was
merged (I confired this by reverting locally and running the test. I suspect
this is caused by incorrect relocation. I tried to fix/debug this further but
no luck. @swegner could you take a look at this?
