Thanks for the details. We’ll notify you in case of any update.

I’m seeing the same problems with these exceptions appearing in the logging, but not only for .docx documents, but also for .txt documents.

The resulting stack trace with .txt documents looks like:

We created a new thread on your behalf. You’ll get further assistance on this issue here.

@Atir_Tahir, do you have any update on this? We purchased GroupDocs conversion for java, but not able to use because of the log entry.

We are still investigating the issue. However, you’ll be notified about the outcomes ASAP.

@Atir_Tahir, do you have any update on this.

@SubratMishra

This issue will be fixed in API version 21.7. If we manage to fix it earlier, you’ll be notified in either case.

Hello,

unfortunately, the error is still in 21.7 as well, at least in the version available from https://repository.groupdocs.com/repo/ that was released on July 8.

UnsatisfiedLinkError means that the GroupDocs conversion library tries to make a Java native JNI call, most certainly by utilizing a helper dll that provides a means of reading values from the Windows registry, but either 1. the required DLL could not be loaded at all or 2. does no provide the necessary function that gets called by GroupDocs. https://docs.oracle.com/javase/8/docs/api/java/lang/UnsatisfiedLinkError.html

The issue affects all versions of GroupDocs.Conversion from 21.1-21.7. Version 20.10.3 does not have the same issues, under Linux we did not notice any problems yet.

  1. Another issue we now experience is a Java 11 incompatibility that appears as soon as any GroupDocs class is initialized, e.g. the License class. This is the first call to GroupDocs we do before converting anything, but it serves just as an example here.

INFO [12 Juli 11:34:56] Trying to load license file from ./license/GroupDocs.Conversion.Java.lic
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.groupdocs.conversion.internal.c.a.ps.internal.gJ.c (file:/D:/pdfconverter/lib/groupdocs-conversion-21.7.jar) to field java.io.ByteArrayInputStream.buf
WARNING: Please consider reporting this to the maintainers of com.groupdocs.conversion.internal.c.a.ps.internal.gJ.c
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release
INFO [12 Juli 11:34:58] License set successfully.

The relevant code is Kotlin, but that makes no difference here, the issue appear in pure Java as well:

private fun loadLicense() {
    if (!licenseLoaded) {
        logger.info("Trying to load license file from {}", Config.LICENSE_PATH)
        val file = File(Config.LICENSE_PATH)
        if (file.exists()) {
            val license = License()
            license.setLicense(Config.LICENSE_PATH)
            licenseLoaded = true
            logger.info("License set successfully.")
        } else {
            logger.info("License file not found")
        }
    }
}

The illegal access warning also appears if we omit the License initialisation and call any later GroupDocs function, namely, Converter.convert() and such, and only appears once (upon the first illegal access registered as always). In this case, too, only versions beyond 20.10.3 seem to be affected, so this behaviour was likely introduced by 21.1 as well. It only goes away with an 8 JDK (of course). We tried both AdoptOpenJDK 11 JRE and JDK and the issue reliably appears upon each start. In 20.10.3, no such warnings have been registered, using the same test app, with just the jre and GroupDocs lib replaced.
For reference, this is the release info from AdoptOpenJDK 11, latest version available:

As we just recently bought the GroupDocs.Conversion Site OEM license for up to 10 developers and need the conversion function rather timely for an important customer project, a remedy would be of definite importance for us. We cannot ship an application issuing exceptions tagged as SEVERE. The conversion itself works anyway in all cases. Thanks for your help!

Thank you for the details. We’re sorry for the inconvenience you are facing. We are further looking into this issue. You’ll be notified as there’s any progress update.

Hello, thanks for your reply. In the meantime, we did some more research to find out what causes the bug, as it hinders us from delivery. As UnsatisfiedLinkError could be caused by a missing DLL in the first place, we checked our app at runtime in SysInternal’s Process Explorer. As soon as we initialize GroupDocs.Conversion, it extracts a file named WindowsNativeCall_x64.dll into some temp dir subfolder and obiously loads it ok (see attached image). javaw.exe is our process, the DLLs that get loaded are listed in the lower panel. Still, the logs spill out messages like these:

Jul 23, 2021 11:27:58 AM com.groupdocs.conversion.internal.c.a.w.internal.Ny u
SEVERE:
java.lang.UnsatisfiedLinkError: ‘java.util.Map com.groupdocs.conversion.internal.c.a.w.WindowsNativeCall.readRegistryStringValues(int, java.lang.String)’

at com.groupdocs.conversion.internal.c.a.w.internal.Kn.oPU(Unknown Source)
(…)

So to our best guesses, the Java part either looks for a different dll or something is wrong with the invocation of that readRegistryStringValues() method. Hope this helps in finding out the cause.
