Reopened to fix JIRA title (this is re: devstudio 10, not 9).

But wanted to also note some other gotchas with using devstudio 10.2.0.AM2 and jdk 9:

a) installer won't run with jdk 9, as noted above
b) installer DOES run with jdk 8, then by editing `jbdevstudio.ini` with these values you can START devstudio 10.2 using jdk 9 ea build 140:

{code}-vm
/opt/jdk-9-ea+140/bin/java
...
-vmargs
--add-modules=java.se.ee{code}

!launchdevstudio10.2.0.AM2-with-jdk9ea140-configuration-settings.png|thumbnail!

However... (and this is why I reopened this issue, really) 

On startup there's no JRE available:

!launchdevstudio10.2.0.AM2-with-jdk9ea140-jre-not-supported.png|thumbnail!

I tried adding JDK 9 ea build 140, and Eclipse rejects the /opt/jdk-9-ea+140 folder with:

{code}
 Target is not a JDK root. System library was not found.
{code}

So... I don't see any way to actually USE devstudio with JDK 9, other than simply launching it and then using JDK 8 for everything else.

> Oracle changed their JDK 1.9 Early Access builds recently. Now the installed jdk reports its version as 9-ea instead of 1.9 used previously. This caused a problem with the JBDS installer: JBDS-3581
> But even if I select jdk 1.8 in the installer and change jbdevstudio.ini to point to my 1.9 installation, JBDS won't start (I'm on Mac).
> It just shows an error saying where to look for log. The log is linked here:
