Simon Steiner reassigned FOP-2897:
----------------------------------
Assignee: Simon Steiner
> Out of memory when loading fonts on Mac - instead it should report font too
> large and continue
> ----------------------------------------------------------------------------------------------
>
> Key: FOP-2897
> URL: https://issues.apache.org/jira/browse/FOP-2897
> Project: FOP
> Issue Type: Bug
> Reporter: Dan Caprioara
> Assignee: Simon Steiner
> Priority: Major
>
> The FontInfoFinder class collects all the fonts from the system. On Mac there
> are huge font files containing icons. This makes FOP break with
> OutOfMemoryError.
> Probably it should show an warning and throw an IOException instead of OOM
> (IOException does not break the entire processing, just skips the current
> font loading, in this way next fonts can be loaded).
> There are two places in the FontInfoFinder class where the OOM should be
> catched:
> {code:java}
> try {
> TTFFile ttf = new TTFFile(false, false);
> FontFileReader reader = new FontFileReader(in);
> ttcNames = ttf.getTTCnames(reader);
> } catch (OutOfMemoryError oom) {
> handleOOM(fontURI);
> }
> {code}
> {code:java}
> try {
> OFFontLoader ttfLoader = new OFFontLoader(fontURI, fontName, true,
> EmbeddingMode.AUTO,
> EncodingMode.AUTO, useKerning, useAdvanced,
> resourceResolver, false, false);
> customFont = ttfLoader.getFont();
> if (this.eventListener != null) {
> customFont.setEventListener(this.eventListener);
> }
> } catch(OutOfMemoryError e) {
> handleOOM(fontURI);
> }
> {code}
> And the handling:
> {code:java}
> private void handleOOM(URI fontURI) throws IOException {
> String sizeMsg = "";
> if ("file".equals(fontURI.getScheme())) {
> sizeMsg = "The font file size was: " + new
> File(fontURI).length() + " bytes";
> }
> throw new IOException(
> "Font is too large. " + sizeMsg);
> }
> {code}
