reckart opened a new issue, #361:
URL: https://github.com/apache/uima-uimaj/issues/361
**Describe the bug**
Opening a CAS (XMI or BCAS - does not matter) in the CAS editor sometimes
fails with an exception.
**To Reproduce**
Steps to reproduce the behavior - works sometimes, sometimes not...
1. Open Eclipse
2. Copy an XMI file into a project
3. Copy a type system file into the project, but do not name it
`TypeSystem.xml`
4. Open the XMI
5. From the open editor select to load the CAS using the type system file
6. Poof
**Expected behavior**
CAS should open.
**Screenshots**
**With XMI**
