Incompatible JVM in GGTS (Eclipse) and JAVA 1.8

Question

Having some problem with running a grails application in GGTS (eclipse) due to upgrade to Java 1.8.

The stack starts with:

I used to run the same application in Java 1.7. My colleagues upgraded to 1.8 and no longer able to run it.

I tested with SUN JDK and now I am on OpenJDK again and that does not help Current JDK openjdk version "1.8.0_40"

JAVA_HOME, JAVA_PATH and any other variable seems to point to the correct JDK installation. I have removed all the previous (JDK 1.6 & 1.7 from the OS to be sure that there is no reference to them).

For some reason GGTS still complains for a wrong JVM. I understand the error might be related to a compiler 1.7 trying to compile files in the 1.8, but I am not sure where this reference is comming from in eclipse.

My Eclipse installation information lists the following under Java:

-vm
/usr/lib64/jvm/jre-1.8.0-openjdk/bin/java
eclipse.home.location=file:/home/arb/dev/applications/ggts-3.6.3.SR1/

It's a problem related to jdk8u40, go back to jdku31. It works in that version. I'm running into the same problem both in windows and linux environments.
