Fix ClassNotFoundException with spaces in TIKA_PATH
Fix ClassNotFoundException with spaces in TIKA_PATH

Tika fails to start when TIKA_PATH contains spaces. A common case would be applications storing the tika jar in `Application Support` on macOS – iscc-cli is an example for this:

https://github.com/iscc/iscc-cli/blob/ad466c3/iscc_cli/__init__.py#L8-L10

Tika server log will contain this (please excuse the german content, should be clear anyway):
Fehler: Hauptklasse Support.iscc-cli.tika-server.jar konnte nicht gefunden oder geladen werden
Ursache: java.lang.ClassNotFoundException: Support.iscc-cli.tika-server.jar

The TIKA_PATH set by iscc-cli: `/Users/strayer/Library/Application Support/iscc-cli`
