* Note: JGit's classes shouldn't be used before SecurityManager is configured.

* For example the class {@link org.eclipse.jgit.util.FS} is used widely in jgit

|

* FS the field DETECTED is initialized and during initialization many system

* operations that SecurityManager can forbid are invoked.

* </p>
|

*
|

* <p>
|

* For this reason this test doesn't extend LocalDiskRepositoryTestCase (it uses

* JGit's classes in setUp() method) and other JGit's utility classes. It's done
|
||||
* to affect SecurityManager as less as possible.
|

|

|

* initialization between different tests run.
