I have two class files compiled differently from the same source code: one with an IDE and another one with a javac call from ant.

I am able to instrument one file (from an IDE) but not the other one (from ant).

This is the exception I am getting:
Exception in thread "main" java.lang.AssertionError

Attached please find both class files. This is the script I have used:
-------------------------------------------------------------------------------------
#!/bin/sh
instrument ()
{
  postfix=$1
  cp UserCode.class.$postfix UserCode.class
  $JAVA_HOME/bin/javap -v UserCode.class 1>${postfix}.javap 2>&1
  $JAVA_HOME/bin/java -ea -jar $JCOV_JAR Instr -t template.xml UserCode.class 1>${postfix}.log 2>&1
  echo $postfix status $?
}
instrument good
instrument bad
-------------------------------------------------------------------------------------
The output I am getting is:
-------------------------------------------------------------------------------------
good status 0
bad status 1
