The plugin works as expected, according to Martin and my own tests. It
will automatically pick up a system RXTX if Eclipse finds one.

Unfortunately, Eclipse seems to be hitting a little problem with
OpenJDK's extension path: It contains /usr/java/packages/lib/ext -
hardcoded into
/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server/libjvm.so - but that is
not used on Debian/Ubuntu. Any Java extensions installed via the package
manager are put into /usr/share/java. I don't know if this is intended
or not.

As a temporary workaround, I found it to be easiest and least intrusive
to just symlink RXTXcomm.jar to /usr/java/packages/lib/ext. Perhaps
there is a way to smash it into the Eclipse classpath, but I haven't
found a proper way to do so.

Paste this into your terminal, restart Eclipse and you're good to go:
sudo mkdir -p /usr/java/packages/lib/ext
sudo ln -s /usr/share/java/RXTXcomm.jar /usr/java/packages/lib/ext/

Title:
  eclipse crashes on loading on serial terminal

Status in “openjdk-6” package in Ubuntu:
  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:

  #
  # A fatal error has been detected by the Java Runtime Environment:

  # Derivative: IcedTea6 1.8
  # Distribution: Ubuntu lucid (development branch), package 6b18-1.8-0ubuntu1
  # Problematic frame:
  # C  [librxtxSerial.so+0x724d]  read_byte_array+0x3d

  # If you would like to submit a bug report, please include

  # The crash happened outside the Java Virtual Machine in native code.
  # See problematic frame for where to report the bug.

  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.
