Jim Challenger created UIMA-4064:
------------------------------------
Summary: DUCC CLI: use a class loader to keep user's classpath and
DUCC's use of 3rd party software segregated.
Key: UIMA-4064
URL: https://issues.apache.org/jira/browse/UIMA-4064
Project: UIMA
Issue Type: Task
Components: DUCC
Affects Versions: 1.1.0-Ducc
Reporter: Jim Challenger
Assignee: Jim Challenger
The most common use of the CLI is by calling its main() from within Eclipse,
with the user's application classpath. If the classpath contains pointers to
3rd party packages used by the CLI, and comes before uima-ducc-cli.jar, the CLI
can malfunction.
Similarly, uima-ducc-cli.jar is often left in the classpath for other than DUCC
CLI usage, and it's own use of 3rd party packages can interfere with
applications.
To remedy this we remove as much 3rd party usage as possible, and use a
classloader for the rest to provide 2-way protection.
