[Bug libgcj/16204] New: File I/O fails on files >= 2^31 bytes (2GB)

[mckinlay at redhat dot com]

libgcj does not appear to support files > 2GB. However the Sun implementation
works fine on the same system & file system. The attached test case fails with
the following error:

$ gij LargeFile
Exception in thread "main" java.io.IOException: Invalid argument
   at gnu.java.nio.channels.FileChannelImpl.seek(long)
(/local/gcc-clean/lib/libgcj.so.6.0.0)
   at gnu.java.nio.channels.FileChannelImpl.position(long)
(/local/gcc-clean/lib/libgcj.so.6.0.0)
   at java.io.RandomAccessFile.seek(long) (/local/gcc-clean/lib/libgcj.so.6.0.0)

It appears we need to enable LFS support. see:

I should note on sane OS's (all *BSD [Darwin is included]) offset_t is always 64bit.
