The implementation of "java.nio.channels.FileChannel" in present CVS head (as of 2005-03-29) "gcc/libjava/gnu/java/nio/channels/FileChannelImpl.java" does not obey the contract for #force(boolean), which states that is should flush/synchronize the channel's file with the storage device.
However, the implementation (in Revision 1.6.32.2, at least) does nothing like it: public void force (boolean metaData) throws IOException { if (!isOpen ()) throw new ClosedChannelException (); } -- Summary: FileChannelImpl.java fails to sync filedescriptor on force() invocation Product: gcc Version: 4.0.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: java AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: martin at egholm-nielsen dot dk CC: gcc-bugs at gcc dot gnu dot org,java-prs at gcc dot gnu dot org,konqueror at gmx dot de http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20684
