How do you configure the spring integration poller after XSD changes have invalidated the fixed-delay and fixed-rate attributes?

Original xml:
<int:poller default="true" task-executor="stepTaskExecutor" fixed-delay="1000">
The fixed-delay attribute is no longer legal, and fails XML parsing in the (eclipse) IDE.
Alternative configuration:
An alternative suggested elsewhere (including https://docs.spring.io/spring-integration/docs/2.0.0.M3/spring-integration-reference/html/samples.html):
<!-- Globally scoped Spring Integration bean resources -->
<!-- see https://stackoverflow.com/questions/73450768/how-to-configure-channels-and-amq-for-spring-batch-integration-where-all-steps-a/73455134#73455134 -->
<!-- see https://stackoverflow.com/questions/28625635/attribute-fixed-rate-is-not-allowed-to-appear-in-element-intpoller -->
<int:poller default="true" task-executor="stepTaskExecutor">
<int:interval-trigger interval="1000"/>
</int:poller>
This passes the XML parsing in the IDE, but fails at runtime

Please advise.

Use Spring Tool Suite (eclipse), or add the spring tools plugin to your eclipse so that the schema is loaded from the jar file instead of from the internet.

IntelliJ: Removing JDK dependency from Artifact Build

Currently using IntelliJ for an IDE.
I inherited a project, and when I went through to make an artifact, I think the compiler is including my local JDK in the build, meaning that if my JRE and JDK are not the same, the program fails on a java.long.SecurityException because a quick signature check of the versions is run when my bundled "artifact" (the jar) runs.
Does anyone know how to make an artifact not bind to a specific JDK/JRE at build time? This program needs to be end user agnostic/independent.
Any help appreciated and thanks folks.
Here is the exact exception found when running the jar file:
Error: A JNI error has occurred, please check your installation and try again

Java Project to Groovy - Libraries don't work

I wrote a program in java and now I want to run it using groovy. I did this as an exercise, so don't question why I haven't programmed in groovy in the first place. ;)
I used many libraries in java, so I copied them to the %GROOVY_HOME%\lib directory. After I did this, I wasn't able to run groovyConsole.exe anymore, so ran groovyConsole.bat (using cmd) to get the error, which is following:
C:\Program Files (x86)\Groovy\Groovy-2.4.11\bin>groovyConsole.bat

The libs I used worked fine in eclipse using java. What can I do?
Additional question:
I found a way to use libraries by loading files. Is there a way to load intire directories with jar files?
this.getClass().classLoader.rootLoader.addURL(new File("file.jar").toURL())

You should not add your script dependencies to %GROOVY_HOME%/lib.
You should instead change your script to declare the dependencies it needs.
One way is to do as you found with the adding JAR URLs to a class loader. If you want to add a directory, list the directory and iterate over the JAR files, something like new File('path/to/dir').eachFileMatch('*.jar') { ...addURL(it.toURI().toURL()) }.
Btw. as you can see in my example, you should never use File.toURL(), this is deprecated since a long time. Always do File.toURI().toURL() instead.
Besides all this, there is a better way to depend on libraries in Groovy scripts, which is Grape. You can read more about it at http://groovy-lang.org/grape.html. Basically you just declare your dependencies with annotations and they are automatically downloaded from a Maven repository and added to the classpath of your script, including any transitive dependencies.

In Install4j, what can I do to fix an java.lang.OutOfMemoryError caused by installing too many installers with too many files?

Some of our testers using the Install4j installers that we produce, are receiving an OurOfMemoryError part way through the process. After a closer inspection, we've narrowed it down to the .install4j/files.log file that Install4j generates. The cumulative entries in this file from all the installers that they run has caused the file to grow larger than 27mb.
My question is what can I do to manage this file so that I don't have this OutOfMemoryError occur anymore? Do I simply have to clear it before every install, or is there a way I can override it to not generate anything at all?
As an alternative, is there any reason I couldn't or shouldn't just delete the .install4j directory?
Here is the stacktrace leading up to the OutOfMemoryError.

On the "Installer->Screens & Actions" step, select the installer and add
-Xmx512m
to the "VM parameters" property. If that does not help add -XX:+HeapDumpOnOutOfMemoryError and post the zipped HPROF snapshot.

Getting Rita.WordNet to work

According to Rita Homepage you just have to download Rita.jar and
WordNet-3.1 and add both to thebuild path of your java project.
I did it like that and everytime i try to use it:
RiWordNet wordNet = new RiWordNet(Test.class.getResource("/WordNet-3.1").getPath());
I get:

The data files are no longer supplied as part of the installation. You need to download the WordNet version for your platform and then pass it to the constructor, as documented here.
