From email:

I have a DOCX file which has a o:gfxdata tag. The OpenXMLContentFilter is caught in an infinite loop in the run method of the thread created in the combineRepeatedFormat method. The read keeps returning the same cbuf value.

public void run()
{
try
{
while((n=br.read(cbuf,0,512))!=-1)
{
for(i=0;i<n;i++)
{
handleOneChar(cbuf[i]);
}
}

The document I am processing cannot be released to the public, so I am trying to create an example for this group.
