Gary Murphy commented on TIKA-1250:
-----------------------------------
The process is looping in ChmLzxBlock around line 613. I put in this hack to
allow the process continue, but I wouldn't expect this to be the correct
solution:
int iterations = 0;
do {
x++;
z <<= 1;
z += getChmSection().checkBit(x);
iterations++;
if (iterations > 1024) {
throw new TikaException("Data cycle in the file
contents");
}
} while ((z = pretreetable[z]) >=
ChmConstants.LZX_MAINTREE_TABLEBITS);
I have a file that will reproduce the problem, but I don't see now to attach
this to the record.
