> Key: NXP-7319
> URL: https://jira.nuxeo.com/browse/NXP-7319
> Project: Nuxeo Enterprise Platform
> Issue Type: Bug
> Components: Transforms / Preview
> Affects Versions: 5.2 GA
> Environment: Windows (XP, Vista, 7, 2008R2)
> Reporter: Mathieu Guillaume
> Assignee: Julien Carsique
> Priority: Major
> Fix For: 5.4.3
>
>
> External command executions sometimes don't return.
> This can be seen in unit tests. Example:
> org.nuxeo.ecm.platform.convert.tests.TestPDFToImage
> Steps to reproduce:
> - install ImageMagick but not Ghostscript
> - run "mvn test" in nuxeo-platform-convert
> -> the process hangs
> If you check the command that is run, it's a simple "convert a.tmp b.png".
> The same command run manually outputs a (verbose) error message and ends.
> Possible analysis:
> The external command is run through the CommandLineExecutor, in this case I
> think it's the ShellExecutor implementation.
> The ShellExecutor doesn't read the error stream.
> Buffer saturation is known to hang processes on some platform (like Windows
> in this case): cf. Process java documentation.
> -> buffer fills -> process hangs -> waitFor() never returns -> the executor
> never returns
