Sorry, what I meant by frequently is that it happens on a number of Mac's.
So far, it appears to not happen on faster Macs with more memory, but on
slower ones with less memory. But on the systems it happens on, its 100%
of the time. I've seen some discussions about this error that indicate it
can be a result of many small objects that need to be garbage collected.
I have noticed that version 2 takes a few seconds to initialize even on
even the fastest systems I have tried it on and am wondering if there is
something happening that could be made more efficient.
No, this is meant to be run once, or when the list of fonts have
changed. You could remove fonts and it would be faster.
On those macs where it happens always, does it change if you increase
-Xmx memory?
Is there any log output besides the exception?
However.... you didn't read my text at all. The very first question,
which was "Are you using the latest version?" Because I see you're not:
org.apache.pdfbox.pdmodel.font.FileSystemFontProvider.addTrueTypeCollection(FileSystemFontProvider.java:344)
that location only existed until the version of 23.10.2015. On 5.11.2015
this was changed, for the very reason you mention (high memory usage).

You mention that this happens "frequently". In theory, this should be
called only once, i.e. when new fonts are discovered. Did you delete the
.pdfbox.cache file to provoke this?

I am finding that the font initialization code is frequently getting this
error on the Mac
According to Sun, the error happens "if too much time is being spent in
garbage collection: if more than 98% of the total time is spent in garbage
collection and less than 2% of the heap is recovered, an OutOfMemoryError
will be thrown.". Seems to be a result of too many small objects combined
with a not so fast computer.
