Unable to run the sample application. about gs-spring-boot

[gregturn]

I'll check it first thing in the morning.

Thanks Greg, but there is no rush, I can just use the previous commit to try out the samples.

[gregturn]

If you can leave a demo of the version of Java you are running and a console output showing it crashing, that would help a lot.

Ah, switching to : JVM: 1.7.0_21 (Oracle Corporation 23.21-b01)

I am able to run commit: b84d2a4

[gregturn]

A) I Java 6, 7, and 8 installed (lots to support). My version of Java 6 is Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609) appears much more up-to-date than the one I saw you list. I can run the "complete" version with this version of Java 6. Not sure if that's the issue.

B) I also see that Spring Boot 0.5.0.M5 is on the tag line. We updated that guide recently to 0.5.0.M6. Perhaps if you delete your workspace and then refetch it, it will run smoother with your version of Java 6 (if 6 is a requirement for you).

[Muzamri]

A) I have installed the latest version for the 1.6 SDK I could find. (You are right about this, ) I managed to get commit: b84d2a4 working. I will list the out put below.

B) Spring Boot 0.5.0.M5 appeared because I reverted to the previous commit (in order to run it successfully). Java 6 is not a requirement for me.

Output:
gs-spring-boot/complete$ ./gradlew -v

Given that it now works, I'll consider the bug was the older version of Java 6.
