Fix code to support multiple classes for tests generation

[gretard]

Hello,
Thank you for the very nice infrastructure for tests generation. I have tried to generate tests at once for multiple classes and spotted a few issues. I am submitting my fix which allowed to generate tests when there are multiple classes specified in the benchmarks.list file, for example:

BCEL=
{
  src=/var/benchmarks/projects/bcel-6.0-src/src/main/java
  bin=/var/benchmarks/projects/bcel-6.0-src/target/classes
  classes=(
    org.apache.bcel.classfile.Utility, org.apache.bcel.verifier.structurals.InstConstraintVisitor
  )
  classpath=(
    /var/benchmarks/projects/bcel-6.0-src/target/classes
  )
}

Thanks for the feedback.
However, I would not recommend the specification of more than one class per benchmark. Notice the focus of the junitcontest project, which is the benchmarking of tools that automatically generate junit tests for Java programs. It is more interesting to know tools performance at class basis. Your fix tough would better suit if we applied the infrastructure for tests generation.

The recommendation for your benchmarks.list file is to generate 2 benchmarks BCEL-1 and BCEL-2, each containing a single class.

Best regards

Thank you for the reply :) I agree on specification of multiple classes, but this fix does not impact anything if you run using a single class, but just updates code to allow to run tests generation against multiple classes as otherwise if you specified multiple classes - generated tests were deleted and an error on second class on invalid parameter were shown :)
