[jira] Commented: (UIMA-487) XCAS operations may slow down when using command line tools

Thilo Goetz commented on UIMA-487:
----------------------------------

I suggest we close this as "won't fix".  Neither "fix" suggestion seems practicable.  Other opinions?

>                 URL: https://issues.apache.org/jira/browse/UIMA-487
>             Project: UIMA
>          Issue Type: Improvement
>          Components: Core Java Framework
>    Affects Versions: 2.1, 2.2
>         Environment: Windows, command line tools in 'bin' folder
>            Reporter: Lev Kozakov

> Problem description: 
> I run documentAnalyzer tool from command line in Win to process 500KB text file by using a sample AE, create XMI output and view it in the built-in Java Viewer. The tool takes about 25 sec to open the output XMI file in the viewer. For bigger files this time may increase significantly. This happens only in those Win machines, where WebSphere products are installed.
> Problem analysis:
> The setUimaClassPath.bat script creates UIMA_CLASSPATH by adding UIMA resources to the default system CLASSPATH, which may already include 3rd party JARs (like eglbatchgen.jar in WebSphere products) containing their own implementation of org.xml.sax packages. Such JAR files may conflict with standard JDK runtime JARs and slow down XCAS related operations. If I manually modify the documentAnalyzer.bat script to use 'clear' UIMA CLASSPATH, w/o default system CLASSPATH, my XMI file opens reasonably fast (< 2 sec).
> Possible suggestions:
> a) not using default system CLASSPATH in the UIMA_CLASSPATH;
> b) create a tool that can identify possible CLASSPATH conflicts and form UIMA_CLASSPATH accordingly.
