Sounds plausible.  gdb doesn't let me print the "ref" variable
directly, however the only register I have that looks like a heap pointer
is $eax:
(gdb) x $eax 0x8180c78: 0x407f1568 (gdb) x 0x407f1568 0x407f1568 <_ZTVN4java4lang6StringE+8>: 0x407f15a0

x /x *(int **)ref

You can have all sorts of fun adding varients of this to breakpoint commands and conditions.
