I am getting below error when I am trying to use the SwingLibrary
java.lang.ClassCastException: SwingLibrary cannot be cast to org.robotframework.javalib.library.RobotJavaLibrary
My Keyword is written like below
*** Keywords ***
Start Demo Application
[Arguments] ${name}
Start Application ${name} java ${MAIN CLASS} 10 seconds ${LIB DIRECTORY}
Take Library Into Use SwingLibrary
I see that my application does get invoked but I get error.
Please help.
EDIT: this issue was fixed in the 1.9.1 release.
The newest version of SwingLibrary no longer implements AnnotationLibrary (which implements RobotJavaLibrary). It has the necessary methods so you should be able to subclass it and use that library with RemoteApplications.
public class RemotableSwingLibrary extends SwingLibrary implements RobotJavaLibrary {}

I have a Groovy script which specifies dependencies using the Grape #Grab annotation. Included with that are a dependency on spring-web to use RestTemplate, and a dependency on slf4j-nop to avoid the Failed to load class "org.slf4j.impl.StaticLoggerBinder" warning.
#!/usr/bin/env groovy
#Grab('org.springframework:spring-web:5.3.18')
#Grab('org.slf4j:slf4j-nop:1.7.36')
import org.springframework.web.client.RestTemplate
new RestTemplate().getForObject('http://www.example.com', String)
However, despite this, I am still getting the SLF4J warning:
$ ./restTemplateLoggingTest.groovy
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
Given that it's a script, it's important that the output not contain extraneous noise, as it may be used and manipulated programmatically.
What can I do to prevent this logging warning from being output when I run my script?
Experimentation has shown that attaching the dependencies to the system classloader using #GrabConfig(systemClassLoader=true) causes the logs to no longer be emitted:
#!/usr/bin/env groovy
#GrabConfig(systemClassLoader=true)
#Grab('org.springframework:spring-web:5.3.18')
#Grab('org.slf4j:slf4j-nop:1.7.36')
import org.springframework.web.client.RestTemplate
new RestTemplate().getForObject('http://www.example.com', String)
I don't know for sure why this is the cause, though I have some vague guesses.
Note that despite addressing the issue, this isn't a use that's described by the Javadocs for GrabConfig#systemClassLoader:
Set to true if you want to use the system classloader when loading the grape. This is normally only required when a core Java class needs to reference the grabbed classes, e.g. for a database driver accessed using DriverManager.
After the installation of PHPunit 8.0.1 I got this error:
Fatal error: Declaration of Symfony\Bundle\FrameworkBundle\Test\KernelTestCase::tearDown() must be compatible with PHPUnit\Framework\TestCase::tearDown()
I am using PHP 7.2
Your tearDown function is not compatible with the function you extend.
You have to add the return type in order to implement the same declaration.
protected function tearDown(): void

the SparkContext in SparkR (v1.5.1) is a
Java ref type org.apache.spark.api.java.JavaSparkContext
however when creating my class:
.jnew("com.example.MyClass","sc")
for my scala class: class TableReader(sc: JavaSparkContext), I'm getting a: java.lang.NoSuchMethodError:
What is this "Java ref type" and how can I get the actual context from it to send through rJava?
SparkR seems to have its own Java interoperability implemented in backend.R. Calls are made in the form SparkR:::newJObject(className, args), though I can't find any specific documentation, other than in tests in the same project.
sqlContext needs to be initialized and relevant jars loaded during startup using --jars {csv jars} or --packages as noted in the documentation.
I am using java1.6,grails 2.0. I want to process Docx documents.For this i have added jars poi-ooxml-3.5-FINAL.jar,ooxml-schemas-1.1.jar.
But in code line this.document = new XWPFDocument(buffInputStream);
i got below error
Class java.lang.ClassNotFoundException

I am trying to add jars either xmlbeans-2.5.0.jar or xbean-2.1.0.jar.
I am getting below error

If i verify my Jre System Library, rt.jar contains this TypeInfo class. how
to solve this problem? Please advice. Thank you.
Hi,
I have tried removing library and used jarscan to search this class. But i didn't find any where. Please help out to figure out how else i can find where is this class and how to resolve this
This happened to me with the JMX MBeanServer class. Groovy was loading one of them with its classloader and so was the JVM.
In your case it sounds like the TypeInfo class exists in rt.jar just fine, but another class loader loads it from that jar (or another jar) again.
Running the JRE with "-verbose:class" showed that double load behavior. Then I moved the offending jar out of my classpath and it worked just fine with the one loaded by Groovy.
I would recommend moving rt.jar out of your classpath, or if you need other classes inside of rt.jar try unjaring and rejaring it without the Type class. That way the classloaders will be forced to use the ones in xmlbeans-2.5.0.jar or xbean-2.1.0.jar.
I have install Groovy 2.1.1 in my unix box. While executing groovysh getting the below error.
Exception in thread "main" java.lang.NoClassDefFoundError: error:
Caused by: java.lang.ClassNotFoundException: error:

Could not find the main class: error:. Program will exit.
What could be the possible root cause for this error...???
Somewhere, you try to use the class error: (and yes, Groovy thinks that the colon is part of the class name), either in the script you execute (i.e. there must be new error: somewhere) or you wrote something like groovysh error: or you import error: (maybe indirectly)
Since you are using IBM J9, according to the Grails FAQ, the J9 need an argument to work well with Groovy, otherwise you may get a NoClassDefFound error:
Add -Xverify:none to JVM arguments
