[Bug classpath/22739] new java.io.FilterWriter(null) should throw NullPointerException

[gcc-bugzilla at gcc dot gnu dot org]

The JDK 1.4.2 API spec states that the contructor
throws NullPointerException if the parameter is null.  
Classpath's javadoc doesn't say this, and it doesn't 
throw the exception either.

I've modified the following Mauve testcase to cover this:

  gnu/testlet/java/io/FilterWriter/write.java

This seems to be because creating a Writer with a null lock object should throw
a NullPointerException (since the FilterWriter out object will be used as
lock). I added an extra mauve test for this and the follow fix in CVS.

        * java/io/Writer.java (Writer(Object)): Check for null lock object.

This fixes both tests.

Thanks,

Mark
