question: private String preProcessSignature ( String signature ) { int index ; if ( ( index = signature . indexOf ( " throws" ) ) > 0 ) { signature = signature . substring ( 0 , index ) ; } while ( ( index = signature . indexOf ( "java.lang." ) ) > 0 ) { signature = signature . substring ( 0 , index ) + signature . substring ( index + 10 , signature . length ( ) ) ; } return signature ; }
target:  This method chops off the throws exceptions, removes "java.lang".
