Bug#617274: scilab: FTBFS: unable to find or use jgoodies-looks

[Aaron M. Ucko]

Package: scilab
Version: 5.3.1-1
Severity: serious
Justification: fails to build from source

Builds of scilab against the latest jgoodies packages are failing with
the errors

> configure: WARNING: Could not find or use the Java package/jar looks used by Scilab Gui - Look and feel (looking for package com.jgoodies.looks.common.RenderingUtils)
> checking looks... no
> configure: error: Could not find or use the Java package/jar jgoodies-looks used by Scilab Gui - Look and feel (looking for package com.jgoodies.looks.common.RenderingUtils)
> checking jgoodies-looks... no
> make: *** [debian/stamp-autotools] Error 1

AFAICT because there is no longer any such class, just
com.jgoodies.common.internal.RenderingUtils from
libjgoodies-common-java.  Could you please take a look?

Thanks!
