Bug#400109: lucene: FTBFS: random, different build failures

[Lucas Nussbaum]

Package: lucene
Version: 1.4.3.dfsg-1.2
Severity: serious
Usertags: grid5000

Hi,

While trying to autobuild lucene, I ran into several different failures.
Over 16 builds, it failed 3 times and timeouted once.

(A) The build timeouted once, while running
    [junit] Testsuite: org.apache.lucene.index.Test

(B) Test org.apache.lucene.search.TestParallelMultiSearcher failed once:
    [junit] Testsuite: org.apache.lucene.search.TestParallelMultiSearcher
    [junit] Test org.apache.lucene.search.TestParallelMultiSearcher FAILED

(C) Test org.apache.lucene.search.TestParallelMultiSearcher returned an
error twice:

    [junit] ------------- Standard Error -----------------
    [junit] Exception in thread "MultiSearcher thread #2"
java.lang.NoClassDefFoundError:

Also, during each compilation (with both successful and failed builds), I got:
     [rmic] RMI Compiling 1 class to

I don't know if this is related.

environment (not unstable).  Internet was not accessible from the build
systems. The builds were processed as root.

About Grid'5000:
