Andreas Lehmkühler commented on PDFBOX-4718:
--------------------------------------------
[~mkl] thanks for the clarification. At least in theory older specs were more
specific about such limitations. The current spec seems to be more realistic as
you pointed out. Another case of, the spec is just a suggestion nothing more :-(
Saying that, I'm going to follow my proposal to restrict the values for a
rectangle at least to max int values when creating it using a COSArray.
[~tilman] your second proposal won't help as long a COSInteger is backed by a
long value. The third suggestion isn't feasible as it is complicated to handle
the underlying information of a Path2d object.
I'm going to fix the issue with debugger, I already have a solution
