        These scripts

        test/jdk/java/lang/invoke/VarHandles/generate-vh-tests.sh
        test/jdk/java/nio/Buffer/genBasic.sh
        test/jdk/java/nio/Buffer/genCopyDirectMemory.sh
        test/jdk/java/nio/Buffer/genOrder.sh
        test/jdk/java/util/Formatter/genBasic.sh

        use the stream preprocessor build.tools.spp.Spp to generate tests from templates. Spp requires that its input and output be specified as

        java build.tools.spp.Spp -i$input -o$output

        and not as

        java build.tools.spp.Spp <$input >$output

        which is to say *not* via stdin and stdout. Presumably Spp was changed without updating these scripts. The scripts now fail to generate the expected tests with a NullPointerException:

        $ sh ./genBasic.sh
        Exception in thread "main" java.lang.NullPointerException
        at java.base/java.io.FileInputStream.<init>(FileInputStream.java:147)
        at java.base/java.io.FileInputStream.<init>(FileInputStream.java:110)
        at build.tools.spp.Spp.main(Spp.java:98)
