Subject Re: Whirr installation issue
Date Wed, 18 Apr 2012 00:41:31 GMT
I hope your are using whirr 0.7.1
whirr installs jdk for you, with 0.7.1 the default is openjdk.

To avoid this JDK issue, I used a custom AMI that has JDK
pre-installed, and in whirr receipe you can specify the Java Home
variable to be used.


Andrei/Karel - thoughts on this?

cheers
