This was filed in forte4j/core and I was asked
to open instead in issuezilla:

Bug description refers to what was seen while
using AS plugin in s1s, but developer felt it was
more general core issue:

Using pseudo localized product, with each message
or label
having additional multibyte text, and using
-fontsize 16
option, running in Chinese locale, following these
steps:
(and see attachment)

from [Runtime] tab in [Explorer] window,
Expand [Server Registry] - [Intalled Servers] -
[Sun ONE AS7]
 - [localhost:4848] , and select
[server1(localhost:80)]
from [Property] tab, click [...] in right side of
[Classpath suffix].

the Move Down button is crushed - but slightly
visible in image.Moving to core netbeans area
since the bug is in the NBClasspath Property
 editor and all users of this editor will face the
same issue in Netbeans
 and or Studio:
Here is our code:
                    Node.Property p;
                   p = new
PropertySupport.ReadWrite (
                       "NbClasspathSuffix",
//NOI18N
                      
org.openide.execution.NbClassPath.class,
                       NbBundle.getMessage
(OneServerInstanceNode.class,"
LBL_classpathsuffix"), //NOI18N
                       NbBundle.getMessage
(OneServerInstanceNode.class,"
DSC_classpathsuffix") //NOI18N
                   ) {
                       public Object getValue () {
                           try{
                            return
si.getNbClasspathSuffix();
                           }
                            catch (Exception ex){
                               
org.openide.ErrorManager.getDefault().not
ify(ex);
                               return null;
                    
                       public void setValue
(Object val){
                           try{
                              
si.setNbClasspathSuffix((org.openide.execu
tion.NbClassPath)val);
                           }
                           catch (Exception ex){
                                
org.openide.ErrorManager.getDefault().no
tify(ex);

                           }


So this editor is for all
org.openide.execution.NbClassPath.class classes
, and belongs to NeTbeans core.

                           }
                   };


       }

This will be marked as blocking task
33246
                       }


Also, the word Classpath does not show fully
