Compiler Discovery Log:
This is not a bug in DrJava, and there is nothing we can do. It is a bug in Java that Oracle needs to fix.
Please try downloading the jar file and using it instead of the exe. That may help. Other than that, I can only suggest keeping your version of Java as up to date as possible, since Oracle may fix this bug.
Here are links to the Oracle bug report and to a bug report for Eclipse:

Thanks! I knew that this is not a bug in dr.java. Since a lot of things are going wrong using java. ArgoUML can't create new and save as. Java EE can't be installed. Even Eclipse is reminding me error coding everywhere, while there isn't one.
I reinstalled java several times but the problem can't be fixed. I am actually going to restore my windows because of the desperation.
As the problem in java exist, and dr.java is the only thing that reply me where did go wrong. I tried to post it here to see if anyone has seen the problem and got a way to solve it as well.
