Description
http://java.net/jira/browse/MACOSX_PORT-754 submitted 2011/11/29 by Yuri Nesterenko
This closed test used to fail in b218 reporting that explicitly set position not used. In b219, however, it is a consistent ArrayIndexOutOfBoundsException: -2. Looks like it may be useful to mention it now.
I'm attaching the test here.
Build: b219

EVALUATION Note that PathGrapics uses a glyph codes as a indexes in an array in order to provide a mapping from glyph codes back to unicode characters. So, it assumes that glyph code is not negative. However it is not true in case of macosx: if there is no glyph in a font for some character, then macosx font support machinery returns negative unicode char in order to indicate that this char requires a substitution (CoreTextSupport.m, lines 92 - 126). Suggested fix just ignores negative glyph codes in PathGrapics. See also comments section.
