Without setting "setenv JAVA_COMPILER NONE" in the build envirnment,
the uninstaller can't be built successfully.
For example,

making ws_for_university_6
echo building: `pwd`
building: /net/harker/prk2/dave/tazinstallja/products_src.sparc/ws_for_university_6
tar cpfF - -C /net/harker/share/tools/Merlin/SDK3.0/classes com | (cd /net/harker/prk2/dave/tazinstallja/products_src.sparc/ws_for_university_6 ;tar xpf - )
tar cpfF - -C /net/harker/prk2/dave/tazinstallja com | (cd /net/harker/prk2/dave/tazinstallja/products_src.sparc/ws_for_university_6; tar xpf - )
