[Bug java/35979] New: JNI method NewStringUTF crashes when passed a NULL pointer

["thomas dot g dot girard at free dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

Hello,

when running java-gnome 4 unit tests, I've found out that gij NewStringUTF
implementation crashes when its argument is NULL. Indeed in natString.cc the
very first line of _Jv_NewStringUTF(const char *bytes) calls strlen(bytes),
without checking whether bytes is NULL or not. Hence the crash.

Sun's implementation does not crash: it returns NULL instead.

However it seems gij implementation is correct according to
http://java.sun.com/docs/books/jni/html/functions.html#65644:
  "Return Values. Returns a local reference to a string object, or NULL if the
string cannot be constructed. Returns NULL if and only if an invocation of this
function has thrown an exception."

Should gij implementation be changed to handle NULL? I've checked that the
crash should still occur on the trunk, r134466
