Jukka Zitting resolved PDFBOX-874.
----------------------------------
Resolution: Fixed
Fix Version/s: 1.3.1
Assignee: Jukka Zitting
Fixed in revision 1025568 by introducing a more more-efficient way of storing
CID ranges in CMaps. The implementation could still be improved, but already
this change drops the memory use of the PDFBox test suite from >128MB to <24MB.
I also explicitly set the memory limit of the test suite to -Xmx64m to better
catch similar problems in the future, while still giving plenty of extra space
to avoid unnecessary test failures due to differences between JVMs.
