Dan Caprioara updated FOP-2897:
---
Description:
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}
