Description

Input files:
Test.groovy

class Test {
    static org.springframework.util.MultiValueMap map = [:] // class from spring-core:4.2.6-RELEASE

    static void main(String[] args) {
        println map
    }
}

compiler-config.groovy

import groovy.transform.CompileStatic
withConfig(configuration)
{ ast(CompileStatic) }

Error:

org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '{}' with class 'java.util.LinkedHashMap' to class 'org.springframework.util.MultiValueMap' due to: groovy.lang.GroovyRuntimeException: Could not find matching constructor for: org.springframework.util.MultiValueMap(java.util.LinkedHashMap)

Expected behavior: either compile time error or handle it correctly during runtime
