> DefaultZipContainerDetector does not support loading of ZipContainerDetectors
> in an OSGi enviroment
> ---------------------------------------------------------------------------------------------------
>
> Key: TIKA-3418
> URL: https://issues.apache.org/jira/browse/TIKA-3418
> Project: Tika
> Issue Type: Improvement
> Components: core, parser
> Affects Versions: 2.0.0
> Reporter: Simon-Shlomo Poil
> Priority: Major
>
> Classes that implements the ZipContainerDetector interface are loaded via the
> ServiceLoader in the DefaultZipContainerDetector (in parsers-zip-commons).
> In an OSGi enviroment the current behaviour is (default constructor) to only
> load classes that a found by the DefaultZipContainerDetector classloader,
> however this will miss ZipContainerDetector classes such as the
> [OPCPackageDetector.java|https://github.com/apache/tika/blob/main/tika-parsers/tika-parsers-standard/tika-parsers-standard-modules/tika-parser-microsoft-module/src/main/java/org/apache/tika/detect/microsoft/ooxml/OPCPackageDetector.java]
> in the
> [tika-parser-microsoft-module|https://github.com/apache/tika/tree/main/tika-parsers/tika-parsers-standard/tika-parsers-standard-modules/tika-parser-microsoft-module].
> The DefaultZipConatinerDetector has constructor to pass a ServiceLoader,
> which in principle could allow loading of dynamic services. However, this
> constructor will load the services only on initialization, which does comply
> with the dynamic natur of an OSGi enviroment where services can come and go
> dynamically.
> Linked to this issue is pull-request that attempts solve this issue following
> a similar strategy of service loading as implemented in the DefaultDetector
> and DefaultParser.
