hi
Because I could not find a proper hit when searching this forum for "Files was unexpected at this time" I am posting some relevant details here.
On a Windows 7 machine I noticed that running the IntegratedWebLogicServer in JDeveloper 12c (12.1.2.0.0) can fail with a message like :
[Starting IntegratedWebLogicServer.]
[waiting for the server to complete its initialization...]
Files was unexpected at this time.
Process exited.
[IntegratedWebLogicServer terminated.]
It seems that this can be related to the value of the PATH environment variable.
If it contains a path (with quotes) like ';"C:\Program Files (x86)\Java\jre7\bin";' (with a space) it will result in "Files was unexpected at this time".
Removing the quotes seems to resolve this (';C:\Program Files (x86)\Java\jre7\bin;') and using the short name could be an alternative (';C:\PROGRA~2\Java\jre7\bin;', try "dir /X" to get the short name).
