**Problem:** On pressing the Copy button we keep waiting in AWT-EventQueue thread in reconstruct() function as we detect that we have missing information for the animated image since we are copying single frame at a time. Due to this infinite wait the application freezes.
**Proposed Fix:** There are conditions in the reconstruct() function that avoid entering the wait() code if we have some error reading the image , etc. So, I added the condition to avoid entering the wait() code if we are copying single frame at a time. This sounded logical to me since if we have incomplete information(single frame) about the animated image we shouldn’t keep waiting, as it leads to infinite wait. After this change I see the GIF image being correctly copied and animated. **Testing:** Added a test for this (bug6176679.java) and tested locally on my Windows machine and on mach5. ------------- Commit messages: - fix executable permission of bug6176679.java - fix executable permission of cupanim.gif - fix for 6176679 Changes: https://git.openjdk.org/jdk/pull/13414/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=13414&range=00 Issue: https://bugs.openjdk.org/browse/JDK-6176679 Stats: 185 lines in 3 files changed: 184 ins; 0 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/13414.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/13414/head:pull/13414 PR: https://git.openjdk.org/jdk/pull/13414
