RAM FileSystem resize throws ArrayOOBE when shrinking in size.
--------------------------------------------------------------
Key: VFS-406
URL: https://issues.apache.org/jira/browse/VFS-406
Project: Commons VFS
Issue Type: Bug
Affects Versions: 2.0
Reporter: Miroslav Pokorny
Im targetting 2.0 as it is the official download.
The fix is quite simple.
FILE: RamFileObject
ORIGINAL
void resize(int newSize)
{
int size = this.size();
byte[] newBuf = new byte[newSize];
System.arraycopy(this.buffer, 0, newBuf, 0, size);
this.buffer = newBuf;
updateLastModified();
}
// when shrinking size > newSize thus an AOOBE will be thrown.
FIXED
void resize(final int newSize) {
final int size = this.size();
final byte[] newBuf = new byte[newSize];
// HACK fixed error which prevented resizing to a small buffer.
System.arraycopy(this.buffer, 0, newBuf, 0, Math.min(newSize, size));
this.buffer = newBuf;
this.updateLastModified();
}
