What steps will reproduce the problem?
1. Open a log file.
2. Run stuff that fills it (further).
3. Try to delete the file (e.g. an external Maven clean build).

What is the expected output? What do you see instead?
Expect delete to succeed.  Maven build fails with inability to delete the
target dir, as that's where log file is.

What version of the product are you using? On what operating system?
0.9.8.1  Win 7

Please provide any additional information below.
Is locking file a requirement?  Is it even possible to not lock it within
the Eclipse setup?
