javah task fails

[LCID Fire]

Binary package hint: ant

In my build.xml I have a javah task for 2 classes. The Javah aborts with:

    [javah] Exception in thread "main" java.lang.ExceptionInInitializerError

It works under jdk not under openjdk

[Onkar Shinde (onkarshinde)]

Looking at the exceptions it looks like the java environment set on your machine is GCJ and not openjdk.

Can you please paste output of command 'ls -l /etc/alternatives/javah'?

[LCID Fire (lcid-fire)]

It says: /etc/alternatives/javah -> /usr/lib/jvm/java-6-openjdk/bin/javah

I even tried
sudo update-java-alternatives -s java-6-sun
- but the output is still the same. So is it valid to change the symlink manually?

[LCID Fire (lcid-fire)]

Woah - I just noticed - there is no bin/javah in java-6-sun!?

[Onkar Shinde (onkarshinde)]

Not sure what the problem is. I think the alternatives are messed up eg. some alternatives pointing to one java while some to others.
You can try doing 'update-java-alternatives -s java-6-openjdk'. Please let us know if this makes any difference.

And javah is part of -jdk packages. So if you want to use Sun JRE/JDK make sure you have sun-java6-jdk package installed.

[LCID Fire (lcid-fire)]

Thanks Onkar for hinting in the right direction.
Seems like I forgot to install the sun-java6-jdk while trying out some configurations. Installing it and setting alternatives to java-6-sun did the trick.
The bug is still valid though - it is not working when I set alternatives to java-6-openjdk.

[Onkar Shinde (onkarshinde)]

Do you have any sample build.xml file that I can try out?

[LCID Fire (lcid-fire)]

Not exactly a sample - but you can try out my original at http://github.com/LCID-Fire/areca/tree/ubuntu.
It's located underneath src

I'm unable to reproduce this. Is there a downloadable package (.dsc) file?

unreproducible, no feedback. closing the report
