Hello Team ,
We have oxygen 24.0 bundled java 8
and our custom frame work jar compiled with java 8 , but when we wanted to assign Author - Actions
and trying to detect our custom actions from framework jar , this is giving
Detection errors:
C:\Program Files\Oxygen XML Editor 24\frameworks\xxx-ditamap-framework\xxx-ditamap-framework.jar - The classes were compiled using a newer version of the Java compiler than the one currently installed.
module-info has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Hi,
The error message is quite clear, your framework java extensions seem to have been compiled with Java 9 and newer compatibility. You need to double check they are compiled with a Java 8 compiler or with a Java 9 compiler in Java 8 compatibility.

Radu

Thanks Radu , we are compiling and building our framework jar using Intellij Gradle and java version is 8 only.
but some where the gradle or Intellij is introducing the class module-info.java and only that specific class compiling with java 9.
ERROR
module-info has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0
don't know what to do , please suggest any inputs here.

Hi,
I don't know exactly how you are building the JAR libraries, if you open the built JAR library using a zip utility like 7-Zip and look in the "META-INF/MANIFEST.MF" file does it say anything about the Java version it was compiled with?
If you send us via email (
support@oxygenxml.com) more details like the JAR libraries, maybe also the part of the gradle script which compiles maybe we'll have more details to help further.
Regards,
Radu

Hi,
Right, the code we have for detecting all custom operations in a JAR library needs to go through all the Java classes in the JAR and possibly one of those Java classes is compiled with Java 9 or newer. But the others are compiled with Java 8 so at runtime things work.

Radu
