Adobe Illustrator CS6 with Java 8?
To activate Illustrator CS6 on El Capitan, you may need to temporarily deactivate the "rootless" mode. To do this, boot into the recovery partition by holding down Cmd-R upon startup. Then use the terminal app to disable "rootless". The command is

csrutil disable


It will advise you to reboot. After rebooting, you can now create the directories

/System/Library/Java/JavaVirtualMachines/1.6.0.jdk


and

/System/Library/Java/Support/Deploy.bundle


Then you may reboot back into recovery mode, and run

csrutil enable


to reactivate the "rootless" mode.
