* initialise for-loop variables before the loop

o the intiialization code of a for-loop used to do that, but no longer
     does so since their automatic transformation to a while-loop. Even
     though the code did not read the value of the for-loop variable
     in case the loop was not entered, the JVM's verifier is not
     sophisticated enough to be able to detect that (it's protected by
     a boolean set in the loop)
