after update Apache POI 4.0 - Property 'http:/

After updating Apache POI from 3.17 to 4.0.0 i'm getting on line:

OPCPackage pck = OPCPackage.open(this.getTemplate());

an exception:

java.lang.IllegalArgumentException: Property 'http://www.oracle.com/xml/jaxp/properties/entityExpansionLimit' is not recognized.

They say in How to disable accessExternalDTD and entityExpansionLimit warnings with logback that i should exclude xerces, but i had this already:

  <dependency>
     <groupId>org.apache.poi</groupId>
     <artifactId>poi</artifactId>
     <version>4.0.0</version>
  </dependency>
  <dependency>
     <groupId>org.apache.poi</groupId>
     <artifactId>poi-ooxml</artifactId>
     <version>4.0.0</version>
     <exclusions>
        <exclusion>
           <groupId>xml-apis</groupId>
           <artifactId>xml-apis</artifactId>
        </exclusion>
        <exclusion>
           <groupId>xerces</groupId>
           <artifactId>xercesImpl</artifactId>
        </exclusion>
     </exclusions>
  </dependency>

My setup:

JDK 8
WildFly 14

Going back to 3.17 fixes the issue.

回答1:

the POI 4.0.0 code works with up to date versions of xerces - the code doesn't even get as far the trying to set the entity expansion limit because it will set the xerces security manager first and stop there - would you be able to try adding an explicit dependency on the latest version of xerces? https://mvnrepository.com/artifact/xerces/xercesImpl/2.12.0

回答2:

This has beed fixed in POI 4.0.1.
