The crash is coming from a broken rxtx library installed from
http://rxtx.qbang.org/eclipse/.

If I remove
~/.eclipse/org.eclipse.platform_3.7.0_155965261/plugins/gnu.io.rxtx.linux.x86_64_2.1.7.3_v20071015/os/linux/x86_64/*.so
and symlink the packaged libraries from /usr/lib/jni/librxtx*.so (Ubuntu
package librxtx-java), it works. A version mismatch warning will be
printed out, but no error and no crash happens.

Removing the "RXTX end-user runtime" plugin in Eclipse does not help,
because "Target Management Terminal" depends on it for serial
connections. The plugin was created to remedy
https://bugs.eclipse.org/bugs/show_bug.cgi?id=175336 - but this does not
account for situations where the rxtx libraries are installed in the
system JNI library directory. Someone should open a new bug report on
the Eclipse bug tracker to request a fix for this.

  New

Bug description:
  When I open a connection to a USB serial port using the RXTX
  (http://rxtx.qbang.org/eclipse) and the Target Manager Terminal
  plugins, Eclipse consistently crashes with no error messages.  The
  follow log is generated:

  Note, I have not had the same problem on 32bit Karmic on a different machine.  I'm able to connect with no problems using ckermit.
  Thanks.
