It's not even supported under Mavericks. You're on your own.
I have InDesign CS 5.5 Vers 7.5.3
Before I downloaded Yosmite to my Hard Rive I downloaded it to an External Hard Drive.
I put InDesign onto this drive. I was prompted to download Java and after doing this InDesign works fine.
I then downloaded to my hard drive on my Late 2009 27" iMac - works fine for me.
