Evosuite tests - IllegalArgumentException Duplicate method name "equals"

[elizabethdinella]

Running with EvoSuite tests causes IllegalArgumentException due to duplicate method. I've tried various inputs to --ppt-omit-pattern, but all result in the same exception.

export JARS=:evosuite-1.2.0.jar:junit-4.12.jar:hamcrest-core-1.3.jar:foo.jar:evosuite-tests/tests.jar

java -cp :$DAIKONDIR/daikon.jar:$JARS daikon.DynComp org.junit.runner.JUnitCore Foo.Foo_ESTest

Output:

I've attached foo.tar.gz a tar file with the source and evosuite-tests I am running with.

Could you find and try a newer version of Evosuite? This one contains over 4000 class files compiled with either Java 2, 3, 4 or 5. We would like to see at least Java 8, but sometimes Java 6 or 7 might work.

[markro49]

I am testing a fix that does not require updating the class files.
