As we do Ladybird (J2SE 1.3.1) and Merlin (J2SE 1.4) Solaris i386/Linux/Win32 builds on our local build machines, we tar up the source workspace using "tar cFFf build-$arch.tar make src ext" and then copy this tar file over to our local build machines and untar it, then do the local builds on those local build machines. That means the build areas aren't valid workspaces. But the package makefile (<ws>/make/pkgdefs/Makefile.master) requires the build area be a valid workspace:
...
JVM_WS:sh= workspace name
...
