Java 6 also on your machine?
Java 8 active/selected at time of setup?
Oracle Java or OpenJDK Java?

ok, pleas run the IDE using:
java -jar sikulix.jar -d 3

... and look in the debug output for the section between
***** show environment for IDE
***** show environment for IDE

there should be a line having something like this:
java 8-64 version 1.8.0_121-b13 vm 25.121-b13 class 52.0 arch x86_64

please report what you have.

ok, the problem is, that your IBM Java does not report the version as Oracle and OpenJDK Java do.
It is the System property java.runtime.version, that usually looks like 1.8....., but with your Java it looks like 8.....

Since there is no way, to adjust this setting from outside, you have to wait, until I have added a workaround in version 1.1.2.

I will make this a bug.
Just watch my activities.

venkatesh (venkat6840) said : #8

so for Sikuli 1.1.1 fix of java 8 i will wait for 1.1.2 version , is there any workaround for Sikuli 1.1.0 as xdotool is already installed on my system , but still im getting error as
[error] RunTimeIDE:*** terminating :command 'xdotool' is not executable

Can you please provide any workaround for this error ?

RaiMan (raimund-hocke) said : #9

please look at the related bug and use version 1.1.2.

RaiMan (raimund-hocke) said : #10

The xdotool problem is solved in version 1.1.x

Can you help with this problem?
