I'm getting this error when compiling Apache Tika the latest version on debian. Any help will be appreciated.

I've downloaded the latest version from tika.apache.org/download.html. Installed maven with aptitude. I use debian. And also have installed sun-java6-jdk. Set JAVA_HOME variable. Then I just go to base tika folder and run "mvn clean install". More interesting is that I could install a few days ago it on another debian server without any problems.

Based on your stack trace, I don't think you're using the Sun JDK. Instead, I think you're using GCJ (the GNU Java stuff) - if you look in the stacktrace you'll see references to libgcj.so which is the giveaway.

I think therefore that what you need to do is use update-alternatives to pick the Sunk JDK / JRE instead of the GNU GCJ one. After that, Tika ought to compile fine.

Try:

update-alternatives --list java
update-alternatives --list javac
update-alternatives --display java
update-alternatives --display javac

The to pick you can use

update-alternatives --config java
update-alternatives --config javac

(You might also want to update jar, jarsigner and a few others too)
