setInput in GIF and PNG readers does not remove previous stream settings

XMLWordPrintable

    • Verified

      When the setInput method of the standard GIF or PNG readers is called, a number
      of instance variables may still hold settings obtained from the previous
      stream. When a read occurs, these settings will not match the new stream
      position and contents, which may result in erroneous behavior.

        This behavior was found by Pravenn Mohan, who supplied a test case where
      the GIF reader throws an OutOfMemoryException. I have streamlined this case
      and will place it in test/javax/imageio/SetInputTest.java.

      Regression test javax/imageio/SetInputTest.java fails with Merlin build build60 on sol2.7, host tiggr. This is a new test since b57.
      Setting state back to NYI because of this failure. eMail al.smith@eng with any questions.
      For test hardware config's, see http://sqesvr.eng/st3/jdk1.4/docs/Merlin-hw.html
