Tim Allison commented on TIKA-2151:
-----------------------------------
I think this may be a duplicate of TIKA-2098. The fix will be in Tika 1.14,
which should be out towards the end of the week.
I just improved the unit test for TIKA-2098 to be:
{noformat}
@Test
public void testMaxLength() throws Exception {
InputStream is = getResourceAsStream("/test-documents/testPDF.pdf");
String content = new Tika().parseToString(is, new Metadata(), 100);
assertTrue(content.length() == 100);
assertContains("Tika - Content", content);
}
{noformat}

> This appears to be caused by the fact that the top-level exception is not of
> type SAXException, meaning that Tika#parseToString doesn't catch it and check
> whether or not its root cause is a WriteLimitReachedException. The result is
> that the first 100000 parsed characters is not returned.
> Here is a quick repro code block:
> Tika tika = new Tika();
> InputStream is =
> this.getClass().getClassLoader().getResourceAsStream("pg100.pdf");
> try {
> String s = tika.parseToString(is);
> System.out.println("It works!");
> } catch ( Exception e ) {
> System.out.println("Tika missed the WriteLimitReachedException");
> }
> Where the pdf used is a pdf that has more than 100000 parseable characters in
> it.
> Not sure I understand all the ins and outs, but we fixed it by extending
> Tika.java and overriding Tika#parseToString to catch Exception instead of
> SAXException.
