Bug#669000: eclipse-platform: Help search function does not work, "invalid format"

[Peter De Wachter]

Package: eclipse-platform
Version: 3.7.2-1
Severity: normal
Tags: patch

When I try to use the Help/Search menu command, I get an "Errors while
indexing" message. The Eclipse error log contains the following information:

    eclipse.buildId=I20110613-1736
    java.version=1.6.0_24
    java.vendor=Sun Microsystems Inc.
    BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=nl_BE
    Command-line arguments:  -os linux -ws gtk -arch x86_64

The problem seems to be that Eclipse failed to retrieve the Lucene version
number. This patch fixes it for me:
