unable to instanciate FastByIDMap<PreferenceArray>, ClassNotFoundException for
com.google.common.base.Preconditions
-------------------------------------------------------------------------------------------------------------------
Key: MAHOUT-615
URL: https://issues.apache.org/jira/browse/MAHOUT-615
Project: Mahout
Issue Type: Bug
Components: collections
Affects Versions: 0.4
Environment: Windows 7, Java 1.6.0.24, reproducable in eclipse helios
and netbeans 6.9
Reporter: bernd hopp
Assignee: Benson Margulies
this code:
FastByIDMap<PreferenceArray> map = new FastByIDMap<PreferenceArray>();
throws an java.lang.ClassNotFoundException, class
com.google.common.base.Preconditions cannot be found.
The error is thrown in FastByIdMap, ln 76, where "Preconditions" cannot be
found. In this project, im using the google web toolkit, which is shipped with
the Preconditions-class, what propably confuses the class-loader. Anyhow, when
im trying the line shown above in netbeans, without any references to gwt, it
fails with the very same exception.
Any questions, suggestions, workarounds etc. appreciated, thanks.
