OS detection in TBX is actually done by strings comparison and used in various places, e.g. System.getProperty("os.name").contains("win32") for Windows.
On some systems, System.getProperty("os.name") now returns "Windows 7" on Windows 7 OS leading to a failure of R/CQP launching on Win 7 because the Linux launching native code is executed instead of Win native code. Result in log is:

<pre>
Failed to start RServe : org.txm.stat.engine.r.RWorkspaceException: ** The Statistics Engine program path is set but we couldn't find it : C:\XXXXXX\R\bin\R.exe

</pre>

h3. Solution 1

* use org.ecplise.core.runtime.Platform.getOS()
* bundle is present in TBX project

h3. Solution 2

* use org.apache.tools.ant.taskdefs.condition.Os
* bundle is present in TBX project

h3. Solution 3

* org.apache.commons.exec.OS
* bundle is NOT present in TBX project

h3. Solution 4

* implement own custom class using System.getProperty("os.name")

h3. Solution 5

* use solution 1, 2 or 3
* centralize/encapsulate the OS detection code in a class, e.g. OSDetector in TBX layer to minimize impact of further string definition potential changes
