[FOP-1178] fop dies due to integer overflow

• Type: Bug
• Status: Closed
• Resolution: Fixed
• Affects Version/s: 0.92
• Component/s: layout/unqualified

Description

TextLayoutManager.java rev=392488
has
private short iTempStart = 0; (Line 145)
which it uses in a loop at line 602:
for (; iTempStart < textArray.length
&& !isSpace(textArray[iTempStart])
&& textArray[iTempStart] != NEWLINE
&& !(iTempStart > iNextStart
&& isBreakChar(textArray[iTempStart - 1]));
iTempStart++) {
...
Looks like in my case textArray was big enough so that length > 32767

I am using fop-0.92beta
Here is the command line:
fop -fo PSC_PTL_Compiler_Design_Spec.fo -pdf PSC_PTL_Compiler_Design_Spec.pdf

and the output:
