[eclipse.org-planning-council] Lucene Bug 382574

[Markus Knauer <mknauer@xxxxxxxxxxxxxxxxx>]

Hi all,

I'd like to get some input from the Planning Council first instead of implementing a fix in EPP. It is about the following bug:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=382574
An
 internal error occurred during: "Indexing help...": 
org.apache.lucene.analysis.TokenStream.incrementToken()Z with Juno RC4 
Java package

There are different version of org.apache.lucene in the Juno repository and the Eclipse Help Search works only with the old 2.9.1 version of the bundle. It seems that at least one other project (Code Recommenders) uses the latest version 3.5.0 which is incompatible to the old one. Unfortunately the Eclipse Help uses the new, incompatible version at runtime.

(1) Code Recommenders would be willing to implement a temporary fix for this that makes them independent from the Lucene 3.5.0 bundle from Orbit, but this would require a rebuild of the Juno repository.

(2) EPP could partially fix this by adding a Java property to the packages that have both Lucene libraries. This would fix the error in the EPP packages only, but everyone else who installs Code Recommenders from the Juno repository would run into this issue then.

Any opinions? Please comment on bug 382574.

Thanks for your feedback,
Markus
