Summary: 6.0.22RC: ArrayIndexOutOfBoundsException from Jasper
when compilation error inside a CDATA block
Product: Tomcat 6
Version: 6.0.20
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
AssignedTo: [email protected]

/webapps/examples/WEB-INF/tags/panel.tagx
Steps to reproduce:
1. Remove /WEB-INF/tags/panel.tag
from the Tomcat Examples webapp and replace it with the attached XML Tag file,
panel.tagx
2. Visit the following page:
http://localhost:8080/examples/jsp/jsp2/tagfiles/panel.jsp
3. The page contains a scriptlet, with a CDATA block that produces
a compilatin error.
Expected result:
Compilation error being reported for line 39,
Integer.parseInt(10);
Actual result:
java.lang.ArrayIndexOutOfBoundsException: 46
org.apache.jasper.compiler.JavacErrorDetail.<init>(JavacErrorDetail.java:111)
4. If I add sufficient number of empty lines after the CDATA block,
ArrayIndexOutOfBoundsException disappears and I can see the compiler error,
but the error lines shown are wrong. The shown lines are below the actual
location of the error.
It looks like this offset in line numbers is due to the size of the CDATA
block.
