Here's what worked:
{code:java}
for (PDField field: acroForm.getFieldTree())
{
if (field instanceof PDTextField)
{
if (field instanceof PDVariableText)
{
for (PDAnnotationWidget widget : field.getWidgets())
{
widget.setAppearance(null);
}
}
}
}
acroForm.refreshAppearances();
{code}

The only problem left is that the second multiline field starts a bit too low,
but IIRC there's another issue about that.
