ImageUtilities.getImageInputStreamSPI don't close streams
---------------------------------------------------------
Key: GEOT-3280
URL: http://jira.codehaus.org/browse/GEOT-3280
Project: GeoTools
Issue Type: Bug
Components: core coverage
Affects Versions: 2.7-M3
Reporter: Daniele Romagnoli
Assignee: Daniele Romagnoli
The ImageUtilities.getImageInputStreamSPI(final Object input) method internally
calls:
spi.createInputStreamInstance(input, usecache, ImageIO.getCacheDirectory());
However, the created inputStream instance is never closed before the method
return.
The method is asked for returning an ImageInputStreamSpi object.
For security checks, it internally uses the retrieved SPI to try creating also
an ImageInputStream, which is never closed.
We should add a finally section which closes that stream.
