Known Issues (Semaphore 5.4.2)
Installation of Studio (Semaphore 5.4.2)
- When installing to Windows you may get a warning about a failure to determine the version of Java in selected JAVA_HOME. Please ignore this message.
- If you do not have Java 11 installed, when you install Semaphore Studio you will be warned that Semaphore Studio requires “Java version 11 or later.” In fact it requires Java 11. Refer to Install third-party software in the Install Semaphore on Windows for details on how to install it.
Classification Server (5.4.2)
- Because of changes to how text is parsed prior to analysis, some inline style changes in PDFs (e.g. emphasised or italic text) may be treated as separate sentences or paragraphs. This could affect evidence finding where that evidence is now spread over multiple zones.
- Because of tokenization issues, Hebrew, Indonesian, Malay, Pashto and Vietnamese are temporarily being removed from the supported language set.
- We have updated our file type detection algorithm. This may change the determined file type for some documents which may affect how the document is parsed. If this is an issue, then remove the “external_parser” entry in the “classify_document” workflow in the file conf/config.xml to revert to the old style.
Stand-alone Linux Publisher (5.4.2)
Note this applies to the standalone publisher only, not the plugin.
- During the Linux installation you may see a spurious message about setting ACL permissions for the tomcat user. Please ignore these.
Knowledge Model Management (5.4.2)
- When downloading configuration or backup files, it is possible that the default Windows zip extractor will report the downloaded file as invalid. This is, however, likely to be due to long file paths in the zip file not being handled correctly by that extractor. An alternative (such as 7-Zip) should be able to correct extract these files.
Semaphore for SharePoint 2013/2016 Integration (4.0 r54942)
The following are known issues with this version of Semaphore for SharePoint 2013/2016:
- Use of custom hierarchical relationship types for synchronization of models may result in incorrect model information in the term store (“has narrower/has broader” hierarchical relationship synchronization works correctly)
- DE2394 - Classification Server version 4.2.0 won't work when adding in CS URL. An error “Version's parameters must be greater than or equal to zero. Parameter name: revision.” is being shown.
