Description

c = "ls";
Runtime.getRuntime().exec(["ls"]);
println "success"
Runtime.getRuntime().exec(["${c}"]);
println "success"

This will print "success" once and then:

Caught: groovy.lang.GroovyRuntimeException: failed to invoke method: groovy.lang.MetaClass$2@1bd0dd4[name: exec params: [class java.lang.String] returns: class java.lang.Process owner: class java.lang.Runtime] on: java.lang.Runtime@d70d7a with arguments: [[ls]]reason: java.lang.IllegalArgumentException: argument type mismatch

We should treat GStrings universally as Strings when talking to Java ... its a tall order but this:

Runtime.getRuntime().exec(["${c}".toString()]);

is definitely not groovy.
