Hello GT-developers,
the following simple testcase uses the GeoTIFFReader class to simply write the
Bounds to the stdout (in an infinite loop).
On Windows (no issue on Linux), I recognized that the GeoTIFF file keeps beeing
locked, i.e. the lock will not get disposed and on every further loop a new
lock on the file is created.
Now I'm not sure if my simple piece of code is conceptionally wrong or if the
GeoTIFFReader class does not close the InputStream.
Please see following testcase.
The Java code:
http://pastie.org/private/n5ajzlccstefwojnjteyeg
You will need to create a folder:
C:\tmp_geo\
You could download the hardcoded GeoTIFF file from (or use your own with EPSG
code):
ftp://ftp.remotesensing.org/pub/geotiff/samples/usgs/i30dem.tif
Paste the GeoTIFF file and the GeoTIFFReaderTest.java to the tmp_geo folder!
You will need the following libraries from GeoTools 2.7.5 (copy these into the
tmp_geo folder!):
gt-api-2.7.5.jar
gt-coverage-2.7.5.jar
gt-epsg-wkt-2.7.5.jar

GeoTIFFReaderTest
Does the lock on the file result from my piece of code or does the
GeoTIFFReader class not release and close the InputStream?
Could someone please verify?
