Nicholas DiPiazza created TIKA-3223:
---------------------------------------
Summary: ForkParser cannot serialize exceptions when using the
ForkParser(Path, ParserFactoryFactory)
Key: TIKA-3223
URL: https://issues.apache.org/jira/browse/TIKA-3223
Project: Tika
Issue Type: Bug
Components: core
Reporter: Nicholas DiPiazza
Using this project as an example
https://github.com/nddipiazza/tika-fork-parser-example
Problems happen when it encounters files that throw a valid exception. Example
002164.ppt from digicorpa is encrypted, so it should throw.
When you use this constructor, you get the expected result:
{code}
try (ForkParser forkParser = new ForkParser(getClass().getClassLoader())) {
{code}
When you use this constructor
{code}
try (ForkParser forkParser = new ForkParser(Paths.get(pathToTikaMainDist), new
ParserFactoryFactory("org.apache.tika.fork.main.CollectingParserFactory",
parserArgs))) {
{code}
You will get a class not found exception - failing to serialize the exceptions.
{code}
org.apache.tika.exception.TikaException: Failed to communicate with a forked
parser process. The process has most likely crashed due to some error like
running out of memory. A new process will be started for the next parsing
request.

But I definitely have those exceptions on both the classpath.
