question: public static Pattern glob2Pattern ( String ... globs ) { final StringBuilder regex = new StringBuilder ( ) ; boolean needOr = false ; for ( String glob : globs ) { if ( needOr ) { regex . append ( '|' ) ; } int i = 0 , len = glob . length ( ) ; while ( i < len ) { char c = glob . charAt ( i ++ ) ; switch ( c ) { case '*' : if ( i < len && glob . charAt ( i ) == '*' ) { regex . append ( ".*" ) ; i ++ ; } else { regex . append ( "[^.]*" ) ; } break ; case '?' : regex . append ( "[^.]" ) ; break ; default : if ( isRegexMeta ( c ) ) { regex . append ( '\\' ) ; } regex . append ( c ) ; } } needOr = true ; } return Pattern . compile ( regex . toString ( ) , 0 ) ; }
target:  Returns a regex pattern that matches on any of the globs on class names (e.g., "sun.misc.**")
