Hi All,
I found a mis-compilation bug that can be reproduced in the master of OpenJDK 9 (http://hg.openjdk.java.net/jdk9/jdk9/) and the latest Oracle JDK 9.0.4+11.
Can anyone help me to report this bug to developers of OpenJDK 9?
Description:
The AOT mode triggers a NegativeArraySizeException while the default mode exits normally.
Input: C0.class (via Google Drive):
