From the Apache log which is found running under FileMaker Server 13 Web Engine:
sh: /Library/FileMaker: No such file or directory
No Java runtime present, requesting install.
2014-12-03 10:47:40.032 java[54908:1107] JLRequestRuntimeInstall: Error calling: CFMessagePortCreateRemote
For reference, the previous installations was also running under FileMaker Server, but version 12.
Once again, Java IS installed, since FileMaker Server requires it.
Still looking for a solution...
