Rather than adding throwErrnoException local function, using standard
jniThrowException in JNIHelp.h.
Also improve the readability:
1. Use throwIOException for
jniThrowExceptionFmt(env, "java/io/IOException", ...);
2. Use throwSoecktException for
jniThrowExceptionFmt(env, "java/net/SocketException", ...);
then the code can fit to one line.
Test: atest TetheringPrivilegedTests (ErrnoException is
test in BpfMapTest)
