Launching explorer giving some bugs

Hello , we are having problem when we try to launch explorer.jar from mac osx lion.

jam gives these errors as shown below:

Jul 19 23:15:51 KadirBASOL.local java[10319] <Error>: CGContextGetCTM: invalid context 0x0
Jul 19 23:15:51 KadirBASOL.local java[10319] <Error>: CGContextSetBaseCTM: invalid context 0x0

Jul 19 23:15:51 KadirBASOL.local java[10319] <Error>: CGContextSetBaseCTM: invalid context 0x0

How can we fix the situation

my java version:

KadirBASOL:bin apple$ java -version
java version "1.7.0_04-ea"
Java(TM) SE Runtime Environment (build 1.7.0_04-ea-b16)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b17, mixed mode)
KadirBASOL:bin apple$

It may be a known issue for Java on MAC in some versions.
