Excluding unexistent package from API: '-excludesig java.net' - doesnt work.

Consider this sample:
--------------------------------------------------------------------------
java -cp binaries/lib/sigtestdev.jar:binaries/lib/exclude.jar com.sun.tdk.signaturetest.Setup -classpath /java/re/jdk/1.5.0/archive/fcs/binaries/solaris-i586/jre/lib/rt.jar -static -filename java.sig -package java.lang -package java.util
---------------------------------------------------------------------------
 java -cp binaries/lib/sigtestdev.jar:binaries/lib/exclude.jar -Dexclude.plugin=com.sun.tdk.exclude.ExcludeList com.sun.tdk.signaturetest.SignatureTest -classpath /java/re/jdk/1.5.0/archive/fcs/binaries/solaris-i586/jre/lib/rt.jar -static -filename java.sig -package java.net -excludesig java.net

Conclusion: it seems -excludesig option of exclude.plugin must have greater priority as -package option.
