The fix for <http://qa.openoffice.org/issues/show_bug.cgi?id=108776>
indeed inadvertently broke compatibility by changing symbol version
names exported from the jvmaccess library.  Thanks to René for finding
this issue.

The effect is that an office installation based on OOo before 3.3
cannot share a URE installation with an office installation based on
OOo 3.3 or later.  Sharing URE installations is only relevant on Linux
and Solaris, not on Windows and Mac OS X, and is probably more of
theoretical than practical concern.

Furthermore, the jvmaccess library is considered a private part of the
URE (see <http://hg.services.openoffice.org/OOO330/file/e13523b45392/ure/source/README#l68>),
so especially no OOo extensions should link against it (which might
otherwise cause problems, causing those extensions to not work across
the OOo 3.3 boundary).  The OOo basis layer code violates this privacy
and does link against the library, causing the incompatibility to be
noticed.

Given this state of affairs, I do not think this issue should be
considered a stopper for OOo 3.3.
