In previous versions all ok, but in Processing 1.1 with Windows / OS X fail

I Have this code:

class PicFilter implements FilenameFilter
{


public boolean accept ( File dir, String name )
{
if ( new File( dir, name ).isDirectory())
{
return false;
}

return (name.endsWith( ".png" ) || name.endsWith( ".jpg" ) ||
name.endsWith( ".gif" )) ;
name = name.toLowerCase();
return true;
}
}

and An error appears:
processing.app.debug.RunnerException: unexpected token: boolean

edit]
The error

This is the error

Cannot reproduce with current HEAD. janebeta7, please download the latest
build (0181) and try with that. You'll find you've got some unreachable
code in your example, but the syntax error is gone.

I change the code and now the error does'nt appear

public static boolean accept ( File dir, String name )
{

if ( new File( dir, name ).isDirectory())
{
return false;
}
name = name.toLowerCase();
String str = "CCCP";
boolean valid =false;
int posjpg = name.indexOf(".png" );
int posgif = name.indexOf(".gif" );
int pospng = name.indexOf(".png" );
if ( posjpg != -1 || posgif != -1 || pospng !=-1) valid = true;
return valid;
