Getting Error using Apache Poi 4 with Java 10

Question

I want to mention that, the whole process runs absolutely fine, when I am using Java 8. But when I am trying the same process with Java 10 I am getting a big Error Message.

I know that poi 3.17 has problems with Java 10, but since https://bz.apache.org/bugzilla/show_bug.cgi?id=62187 -- the developer of poi 4 say that now it should be possible to run poi 4 with java 10, I am confused and dont know how to solve my issue?

Could you try adding an explicit dependency on an up to date copy of xerces, eg stackoverflow.com/a/52283380/987959 ? — PJ Fanning

I am not working with Maven. I use Intellij for my coding and adding the Libaries which I need as Jar files. Actually I make use of following Libraries: 1)poi-4.0.0 --- 2)xerces-2_12_0 --- 3)xml-commons-external-1.4.01 — Javed Was

@JavedWas why not use Maven? IntelliJ can use Maven poms directly as project files. — jwenting

The work I am doing needs to work offline - and a couple of weeks a ago I found out, that Intellij can download Maven dependencies for offline usage. So now i also can use Maven. I hope this wil solve my problem :D - Thank you — Javed Was

I've added a dependency to xercesImpl in my Gradle setup (build.gradle) which fixes this issue:

"xerces:xercesImpl:2.12.0",

If you are using Maven, add:

<dependency>
    <groupId>xerces</groupId>
    <artifactId>xercesImpl</artifactId>
    <version>2.12.0</version>
</dependency>

You are likely missing one of the transitive dependencies of Xerces, at least xml-apis.jar, but there are also more jar-files in the binary distribution at http://xerces.apache.org/mirrors.cgi which you might need as well.
