we're definitely on the right track. After changing the loop in TestProblem3
the tests run through. However, now I have two failing tests:

Failed tests:
  testMinpackBrownDennis(org.apache.commons.math.estimation.MinpackTest)

================ %< ===============

The JDK I use is one of the last JRockit versions available as separate
download from former BEA:

================ %< ===============
$ java -version
java version "1.5.0_14"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_14-b03)
BEA JRockit(R) (build
R27.5.0-110_CR366951-97327-1.5.0_14-20080408-1711-linux-ia32, compiled
mode)
================ %< ===============

Since IBM JDK 1.5 does not run with Maven, I tried that one with Ant and it
worked fine.

Regards,
Jörg
