String strTmpdir = ((String) AccessController.doPrivileged(new GetPropertyAction("java.io.tmpdir")));

I'm using NETBeans and I have this warning
...\JIntFrmRunTests.java:266: warning: [unchecked] unchecked conversion
found   : sun.security.action.GetPropertyAction
required: java.security.PrivilegedAction<T>
                            String strTmpdir = ((String) AccessController.doPrivileged(new GetPropertyAction("java.io.tmpdir")));

What shall I do to remove this warning?

thanks

Can you do:

String strTmpdir = AccessController.doPrivileged(new GetPropertyAction<String>("java.io.tmpdir")) ;

?

Not sure it will work though...

Nope

...\JIntFrmRunTests.java:267: type sun.security.action.GetPropertyAction does not take parameters
                            String strTmpdir = AccessController.doPrivileged(new GetPropertyAction<String>("java.io.tmpdir")) ;

How about:

String strTmpdir = AccessController<String>.doPrivileged(new GetPropertyAction("java.io.tmpdir")) ;

The new typed parameters hurt my head ;-)

This will be points to me :)

Why not use 'System.getProperty("java.io.tmpdir")'?
