visad-installation

hi all:

i am trying to compile visad classes. everything works fine to a point where
i get the error below:


        javac -J-mx64m ..\ij\gui\*.java
        javac -J-mx64m ..\ij\io\*.java
        javac -J-mx64m ..\ij\measure\*.java
        javac -J-mx64m ..\ij\plugin\*.java
..\ij\plugin\FolderOpener.java:247: unreachable statement
                        return 0;;
                                 ^
Note: ..\ij\plugin\PGM_Reader.java uses or overrides a deprecated API.

1 error
NMAKE : fatal error U1077: 'C:\WINDOWS\system32\cmd.exe' : return code '0x1'
Stop.

C:\visad>

any ideas on why it throws this fatal error ?
my classpath=c:\;.
