It seems that if MappedByteBuffer is using Unsa= fe operations to load a truncated file into memory that a SEGV would be expect= ed.=20 I wonder how this generates an internal error on other Operating Systems. I saw a comment in the test that windows throws an error when you try to trun= cate a file that has an open MappedByteBuffer, maybe FreeBSD should as well. try { fc.truncate(TRUNCATED_FILE_SIZE); truncated =3D true; } catch (IOException ioe) { // probably on Windows where a file cannot be truncated when // there is a file mapping. truncated =3D false; } --=20 You are receiving this mail because: You are the assignee for the bug.=
