Subject [jira] [Created] (TIKA-2812) NPE when parsing text with write limit set on IBM JDK
Date Fri, 11 Jan 2019 11:22:00 GMT
Sergiy Shyrkov created TIKA-2812:
------------------------------------

             Summary: NPE when parsing text with write limit set on IBM JDK
                 Key: TIKA-2812
                 URL: https://issues.apache.org/jira/browse/TIKA-2812
             Project: Tika
          Issue Type: Bug
          Components: core
    Affects Versions: 1.20
         Environment: IBM JDK 8
            Reporter: Sergiy Shyrkov
         Attachments: TikaTest.java, output-ibm-jdk-tika-1.14.txt, output-ibm-jdk-tika-1.20.txt,
output-open-jdk-tika-1.20.txt, output-oracle-jdk-tika-1.20.txt, test.txt

We have updated Tika from version 1.14 to recently released 1.20 and are now experiencing
an issue with parsing of texts when write limit is set (we are using {{WriteOutContentHandler}})
on IBM JDK 8.

Test class [^TikaTest.java] and test file [^test.txt] are attached.

The issue is present on IBM JDK 8 [^output-ibm-jdk-tika-1.20.txt], but not on Oracle [^output-oracle-jdk-tika-1.20.txt]
or Open JDK 8 [^output-open-jdk-tika-1.20.txt].

With Tika 1.14 we had no this issue [^output-ibm-jdk-tika-1.14.txt].

Analysis:
With the fix in TIKA-2668 ([https://github.com/apache/tika/commit/89a588e4d8d2aa44a9d3c965d514c18c7d3c134d#diff-5a28529cf32968d35a5036172cd8f74fL41)] a
line was removed from the constructor of the {{TaggedSAXException}} class:
{code}
initCause(original); // SAXException has it's own chaining mechanism!
{code}

Bringing the line back, solves our issue with JDK 8, but breaks the things on JDK 11.

Is there any chance the class {{TaggedSAXException}} can be made compatible with JDK 8 and
JDK 11 (both Oracle/OpenJDK and IBM one)?

Thank you in advance!

Kind regards
Sergiy Shyrkov
