Hi all,

Downloaded latest release of gatling . “gatling-charts-highcharts-2.0.0-RC4”

When am trying to open the recorder from bin, getting this error:

Unsupported major.minor version 51.0 means the java program you’re using is compiled against JDK7 but you’re using an older version.

Indeed, Gatling requires at least JDK7u6: http://gatling.io/docs/2.0.0-RC4/general/operations.html#java-version
