If the workspace directory (or any parent) contains the word "unix", the build fails in java.desktop-libs. There are several libraries here that use the EXCLUDE_SRC_FILTER option of SetupJdkLibrary to filter away the src/java.desktop/unix/lib* dirs. This option incorrectly includes the whole absolute path of each source file when applying the filter, so when the workspace dir contains "unix", these libraries get no source files at all.
