JNI Class Descriptors look like Lclass/name/with/dot/replaced/by/slash;
Ljava/lang/String; is a legal JNI Class Descriptor, but Ljava.lang.String; is
not. The second form is accepted in for example Method Descriptors given to
GetMethodID as shown in this email:
http://gcc.gnu.org/ml/java-patches/2004-q2/msg00831.html
It would be nice if there was at least a warning that non-standard Class
Descriptors are accepted since this will likely fail on other JNI
implementations (like the jamvm one).

The problem is that JNI uses the "slash format" while GCJ uses the "dot format" internally. We could perhaps switch to using "slash format" internally in GCJ, although this could make some things a little less efficient. In any case, IMO libgcj should never accept "dot format" for JNI. -- What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Ever Confirmed| |1 Last reconfirmed|0000-00-00 00:00:00 |2004-06-30 03:26:57 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16281 ^ permalink raw reply [flat|nested] 4+ messages in thread
