The related test-case was fixed as part of bug #64516, so hopefully this
problem is now resolved in nightly builds, although there remain some more
issues with shifting/cloning...

In r1752996 I have narrowed down the testcase slightly, after the first
shifting, only removing row 0 and then trying to access row 1 causes the
exception.

Is there any temporary workarounds available for this problem?

It depends on if someone contributes a patch that fixes the bug. Those who are
not affected by the bug are less likely to spend time fixing the bug.

I simplified this to creating empty rows, and the exception was still thrown by
the second shiftRows call. r1749300.
This isolates the problem to the CTRows causing the disconnected XML value.

Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet();
for (int r=0; r<=4; r++) {
sheet.createRow(r);
}

// Shift the 2nd row on top of the 0th row
sheet.shiftRows(2, 2, -2);
sheet.shiftRows(3, 3, -3);

Verified this affects the current trunk (pre-3.15-beta2). Added a disabled unit
test in r1749295.

XmlValueDisconnectedExceptions occur because the links between nodes in the DOM
(XML tree) are broken. This can happen when a node is freed by one node but
still weakly linked to by another node. This only causes problems when the
second node tries to traverse the broken link.
