Bug ID: 69288
Summary: SXSSFSheet constructor unnecessarily rethrows
NoClassDefFoundError on Android
Product: POI
Version: unspecified
Hardware: Other
OS: other
Status: NEW
Severity: normal
Priority: P2
Component: SXSSF
Assignee: dev@poi.apache.org
Reporter: samo.re...@gmail.com
Target Milestone: ---
In the SXSSFSheet constructor, there is this line:
_autoSizeColumnTracker = new AutoSizeColumnTracker(this);
On Android this throws NoClassDefFoundError:
java.lang.NoClassDefFoundError: Failed resolution of:
Ljava/awt/font/FontRenderContext;
at org.apache.poi.ss.util.SheetUtil.<clinit>(SheetUtil.java:98)
at
org.apache.poi.xssf.streaming.AutoSizeColumnTracker.<init>(AutoSizeColumnTracker.java:117)
at org.apache.poi.xssf.streaming.SXSSFSheet.<init>(SXSSFSheet.java:106)
at
org.apache.poi.xssf.streaming.SXSSFWorkbook.createAndRegisterSXSSFSheet(SXSSFWorkbook.java:694)
at
org.apache.poi.xssf.streaming.SXSSFWorkbook.createSheet(SXSSFWorkbook.java:688)
...
This is understandable, Android doesn't have AWT classes.
There is a try/catch around this line, but the check inside is probably too
strict:
try {
_autoSizeColumnTracker = new AutoSizeColumnTracker(this);
} catch (UnsatisfiedLinkError | NoClassDefFoundError | InternalError |
// thrown when no fonts are available in the workbook
IndexOutOfBoundsException e) {
// only handle special NoClassDefFound
if (!e.getMessage().contains("X11FontManager")) {
// close temporary resources when throwing exception in the constructor
_writer.close();
throw e;
}
LOG.atWarn()
.withThrowable(e)
.log("Failed to create AutoSizeColumnTracker, possibly due to fonts
not being installed in your OS");
}
The exception is caught, but then rethrown. If the if condition was changed to:
if (!e.getMessage().contains("X11FontManager") &&
!e.getMessage().contains("FontRenderContext")) {
then we might be able to use the streaming APIs on Android.
