Bug ID: 66230
Summary: SheetUtil.getDefaultCharWidth() should handle AWT NPE
instead of failing
Product: POI
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: major
Priority: P2
Component: SS Common
Assignee: dev@poi.apache.org
Reporter: pat...@rufflar.com
Target Milestone: ---
Apache POI (e.g. SheetUtil.getDefaultCharWidth()) fails with a NPE when using
auto-sized columns and some system packages (e.g. fontconfig) are not installed
on the system.
Instead of failing, POI should rather catch the NPE and disable column
auto-sizing like it is doing in other scenarios/exception types.
Stacktrace (from poi 3.17):
java.lang.NullPointerException
