[Bug 1081057] [NEW] Scripting plugin does not work (classpath problem)

Public bug reported:

Reproduce:

Install

* freemind
* freemind-plugins-script

Open Freemind, create a new map, create a node, open the script editor
via

Tools > Script Editor

Create a new script

Actions > New Script

Enter a very basic script (this one should set the node text to "Test
Value")

 = "Test Value"

And run it

Actions > Run

What should happen : the node text changes to "Test Value"
What does happen : Nothing visible in UI
Stack trace is logged to STDERR (see below)

Problem is a classpath issue : package `groovy` correctly depends on the
libasm3-java package which contains the interface listed as
NoClassDefFoundError

Classpath obtained from installed freemind starter script ==

::/usr/share/freemind/lib/freemind.jar:/usr/share/java/SimplyHTML.jar:/usr/share/java
/gnu-regexp.jar:/usr/share/java/jibx-
run-1.1.6a.jar:/usr/share/java/xpp3.jar:/usr/share/freemind/lib/bindings.jar:/usr/share/java/forms.jar:/usr/share/freemind

Suggestion : starter script should construct additional classpath
entries from a file installed with the plugins, e.g. put entries in
files in /etc/freemind/classpath.d/ or
/usr/share/freemind/plugins/classpath.d/ (or wherever is most
appropriate for debian pacakges)

Is there a standard way of constructing classpaths based on this sort of
thing in Debian? If not, there probably should be.

Adding the following entries to the classpath renders the test above
functional ; the "full" versions of these jars may be overkill, I
suppose.

/usr/share/java/asm3-all.jar
/usr/share/java/antlrall.jar
