While comparing list of exported symbols, libgcj_bc.so.1 hasn't dropped any
symbols from 4.3 (correct, hasn't changed SONAME), but libgcj.so.10 dropped
_Jv_CreateJavaVM and _Jv_GetStringChars symbols compared to libgcj.so.9.
That wouldn't normally be an issue (they have different SONAME), but in this
case, as they are listed in libgcj_bc.so and thus part of libgcj_bc.so.1
ABI, this is an ABI break. Seems _Jv_CreateJavaVM is still exported from
libgcj.so.10, but unlike 4.3 as extern "C++" name (mangled,
_Z16_Jv_CreateJavaVMP14_Jv_VMInitArgs), while previously
it was exported as extern "C". _Jv_GetStringChars isn't exported at all.
Seen at least on x86_64-linux and i686-linux.
Can this be fixed before 4.4 release?

------- Comment #1 from aph at gcc dot gnu dot org 2009-01-16 14:59 -------
Thanks for looking.
As far as I can see _Jv_GetStringChars has been extern inline forever, so
doesn't matter. Probably should have a matching definition, but will never be
called.
_Jv_CreateJavaVM in libgcj.so.9 is:
00000032e57a5690 T _Z16_Jv_CreateJavaVMP14_Jv_VMInitArgs
in libgcj.so.7 is:
0000000001071e30 T _Z16_Jv_CreateJavaVMP14_Jv_VMInitArgs
This change was made in 2005. It seems to have been a mistake, but no-one
noticed. The only way to fix it will be to add an alias.

Then _Jv_GetStringChars should be dropped from libgcj_bc.so too.
And for the other function, I think adding a "C" alias in libgcj.so.* and
a C++ in libgcj_bc.so wouldn't hurt.
