Description

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(); }
