Platform: Unix
Test O/S: SunOS 5.8

Steps to reproduce:

1) Install the JDK 1.3.1 b18 (ex: [your home directory]/j2sdk1_3_1) and set JAVA_HOME to this JDK
2) Change 777 permission to all the applets under
[your home directory]/j2sdk1_3_1/demo/applets directory.
3) Use HTMLConverter to convert Animator applets:

%java -jar /net/altair.east/terra/space2/plugin/jmelvin/ladybird/ext/plugin/tmp/solaris/sparc/converter/htmlconv1_3_1.jar -source
[your home directory]j2sdk1_3_1/demo/applets/Animator "*.html"

Applets should be converted properly. However if we leave OUT the quote, then there is no applet found.
In short, the filespecs must be quoted. But the instruction does not mention this. It won't work on Unix if users follow Filespecs in the instruction:

hungn@systemtest:/home/hungn( 56 )% java -jar /net/altair.east/terra/space2/plugin/jmelvin/ladybird/ext/plugin/tmp/solaris/sparc/converter/htmlconv1_3_1.jar HTMLConverter -help

Usage: java -jar htmlconv1_3_1.jar [-option1 value1 [-option2 value2 [...]]] [-simulate] [filespecs]
