Observed on S1597, but very likely occurs on earlier post ESH reintegration snap…shots too. With OH running on a Windows machine, scripts do not load at startup. After saving a script, the script is loaded. I've reproduced this in a test environment while troubleshooting the issue someone had [reported in the forum](https://community.openhab.org/t/jsr223-jython-simplified-rule-definition-similar-to-rules-dsl-and-universal-decorator/53252/172?u=5iver). If the issue does not occur on a build prior to one that includes #724, then the changes to ScriptFileWatcher could be the cause, but I don't see that PR causing an issue for Windows. I plan to investigate further.

But when I observed this, the logs were working. I haven’t tested on a Windows install in a couple months, so this could be something new. I’ll boot over to Windows and take a look sometime later today.

-Xbootclasspath/a:D:\OpenHAB\openHAB_2-5_M2\conf\automation\jython\jython-standalone-2.7.1.jar -Dpython.home=D:\OpenHAB\openHAB_2-5_M2\conf\automation\jython -Dpython.path=D:\OpenHAB\openHAB_2-5_M2\conf\automation\lib\python

Are you missing the set EXTRA_JAVA_OPTS= from the beginning of this line? From the docs…

REM Add to the top of the file
set EXTRA_JAVA_OPTS=-Xbootclasspath/a:C:\openhab2\conf\automation\jython\jython-standalone-2.7.0.jar -Dpython.home=C:\openhab2\conf\automation\jython -Dpython.path=C:\openhab2\conf\automation\lib\python
