Description
FULL PRODUCT VERSION : java version " 1.7.0_25 " Java(TM) SE Runtime Environment (build 1.7.0_25-b15) Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode) ADDITIONAL OS VERSION INFORMATION : Darwin Kernel Version 11.4.2: Thu Aug 23 16:25:48 PDT 2012; root:xnu-1699.32.7~1/RELEASE_X86_64 x86_64 A DESCRIPTION OF THE PROBLEM : While inspecting PNG header, com.sun.imageio.plugins.wbmp.WBMPImageReaderSpi.canDecodeInput() throws IOException because the first byte of a PNG header is 137 (unsigned byte), which was read as a negative value (signed byte). Hence it doesn't call " stream.reset() " and when the image is passed to PNGImageReader, the first byte is skipped and the reader falsely throws " javax.imageio.IIOException: Bad PNG signature! " . REGRESSION. Last worked in version 6u43 STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : just call javax.imageio.ImageIO.read() with any PNG file. EXPECTED VERSUS ACTUAL BEHAVIOR : EXPECTED - Should read a PNG file successfully. ACTUAL - It throws " javax.imageio.IIOException: Bad PNG signature! " exception.
