[Bug classpath/22905] New: gnu.java.nio.channels.FileChannelImp map, lock, unlock methods not implemented

[pinskia at gcc dot gnu dot org]

in the file gnujava
iochannelsFileChannelImpl.java there are 3 native methods:



public native MappedByteBuffer mapImpl(char mode, long position, int size)

private native boolean lock(long position, long size, boolean shared, boolean 
wait)

public native void unlock(long pos, long len)



which are supposed to be implemented in the 
nativejnijava-niognu_java_nio_channels_FileChannelImpl.c, but they are not, 
"not implemented exception" is thrown instead.



Also http://www.kaffe.org/~stuart/japi/htmlout/h-jdk14-classpath.html says that 
java.nio is 100% implemented but these methods are missing.

Trygve Laugstol has a patch for this. We are currently doing the copyright 
assignment work. Then his stuff can go in.
