Problem description:
I am running running the gradle test task on a Grails 3.1.4 project on my Windows 7 Laptop and all tests pass.
I am running the same gradle task on a remote Virtual machine CentOs 7, but some of the tests crash with the following error:

I cropped some portions of the stacktrace. Let me know if you think there are hidden hints.
This is the Test Class:
import grails.test.mixin.integration.Integration
import grails.transaction.Rollback
import groovyx.net.http.RESTClient
import spock.lang.Specification
import java.util.regex.Pattern
import static groovyx.net.http.ContentType.JSON
@Integration
@Rollback
class MyClassApplicationVersionControllerTest extends Specification {
RESTClient restClient = new RESTClient('http://localhost:6543')
def 'MyClass Version Controller Test 1'() {
when: 'version url is called'
def response = restClient.get(
path: "/MyClass/MyClassVersion/getCurrentVersion"
)
then: ''
println(response.responseData)
assert Pattern.matches("01.01.01.*" , response.responseData.toString()) == true
}
}
This is the underlying Controller Class:
import grails.converters.JSON
import grails.rest.RestfulController
import org.apache.commons.io.FileUtils
import java.nio.charset.Charset
import java.nio.file.Files
import java.nio.file.Paths
class MyClassVersionController extends RestfulController{
MyClassVersionController() {
super(MyClassSystem)
}
def getCurrentVersion(){
BufferedReader br = new BufferedReader(new InputStreamReader(this.class.classLoader.getResourceAsStream('version.txt')))
def version = br.readLine()
br.close();
render version
}
}
I checked the Gradle Versions: on both environments its Gradle 2.12. The JVM-Version is 1.8.
Can you give me hints or the solution?
