OK great, no overlinking required in java.

Thanks a lot Emmanuel and thanks Midix for your detailed report and
quick follow-up.

Cheers,

It's working again with libmail-java/1.6.1-2.

Thanks

I've just uploaded libmail-java/1.6.1-2 with the Class-Path attribute
pointing to activation.jar. Is it any better ?

This seems to be a CLASSPATH issue due to the new dependency on
javax.activation of javax.mail.

I do not know enough about java library jar good practices to know if
the classpath should be set in mail.jar or explicitly in davmail.jar
though (as it is not davmail that depends on activation.jar but
mail.jar).

The following patch (or built package at
https://sml.zincube.net/~niol/tmp/davmail_4.8.3.2554-2+test894689+1_amd64.changes
) may fix the problem by adding activation.jar in davmail.jar's
classpath:

Bug#894689: davmail does not work with java-9-openjdk

[Mikko Rapeli]

Package: davmail
Version: 4.8.3.2554-2
Severity: normal

Dear Maintainer,
   
davmail fails to work correctly with latest java-9-openjdk in Debian
unstable.

Fetching and sending messages fails with an exception trace:

Exception in thread "ImapConnection-51322" java.lang.NoClassDefFoundError: 
javax/activation/DataHandler

at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:496)
... 6 more

Since downgrading davmail did not help, I checked if I have multiple java
JRE versions installed and it turned out I do:

# dpkg -l |grep openjdk
ii  openjdk-8-jre:amd64   8u162-b12-1   
  amd64OpenJDK Java runtime, using Hotspot JIT
ii  openjdk-8-jre-headless:amd64  8u162-b12-1   
  amd64OpenJDK Java runtime, using Hotspot JIT (headless)
ii  openjdk-9-jre:amd64   9.0.4+12-4
  amd64OpenJDK Java runtime, using Hotspot JIT
ii  openjdk-9-jre-headless:amd64  9.0.4+12-4
  amd64OpenJDK Java runtime, using Hotspot JIT (headless)

Then I used 'update-alternatives --all' command and switched all java related
tools from openjdk-9 to openjdk-8. After restarting davmail, I can now again
send and receive messages with it.

Maybe davmail could depend on openjdk-8-jre-headless until the root
causes are fixed.

Thanks,

-Mikko
