Error building grails app

Question

I have an Java version 1.6.0_37 and Grails 1.3.9 . When building my app I get a following error:

Compilation error: java.lang.UnsupportedClassVersionError: org/codehaus/groovy/grails/plugins/springsecurity/SpringSecurityUtils : Unsupported major.minor version 51.0

I've found out that the code 51 means a conflict with Java version 1.7. But I removed that Java version.

How do I fix this?

You need to recompile the org/codehaus/groovy/grails/plugins/springsecurity/SpringSecurityUtils class under JDK 1.6. It's source can be found here .
