[GitHub] [uima-uimaj] azazali30 opened a new issue, #313: concurrent modification exception on high load
azazali30 opened a new issue, #313:
URL: https://github.com/apache/uima-uimaj/issues/313
**Describe the bug**
A clear and concise description of what the bug is.
**To Reproduce**
Steps to reproduce the behavior:
1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error
**Expected behavior**
we are running our tests with 1000 concurrent users simulated using Gatling test runner. we see this exception in our logs and we are not able to reproduce with less concurrent users or in local env. So i cannot provide any particular steps to reproduce.
**Screenshots**

You can have a look at these methods and see whether e.g. adding a synchronize block to them resolves the problem:
```

at org.apache.uima.analysis_engine.impl.ResultSpecification_impl.compileIfNeeded(ResultSpecification_impl.java:583)
at org.apache.uima.analysis_engine.impl.ResultSpecification_impl.intersect(ResultSpecification_impl.java:703)
```
That said, UIMA 2.x is no longer maintained. Best upgrade to 3.x and check if the issue persists.
