*** This bug is a duplicate of bug 1699772 *** https://bugs.launchpad.net/bugs/1699772
THIS COMMENT ALSO ADDED TO (PARENT) BUG https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1699772 However, that bug has FixReleased (at least for 64-bit JVMs). I guess it should be also fixed for 32-bit JVMs launched from C on 64-bit kernel. I'm not sure, whether it would be better adding this comment just to Bug 1699772, or just to this ("duplicate") Bug 1700270, or creating just another bug ID. I have chosen adding it to Bug 1699772 and also here, since my code example is based on previously-provided test.c which I downloaded from Bug 1700270.

The attached repro case: - compiles a java class - compiles a C program that initialises the JVM and calls a static method from the java class - launch the compiled C program. Expected result: the c program should execute the Java method and print some numbers in the terminal Actual result: the c program segfaults while initialising the JVM reverting to linux 4.10.0-22-generic amd64 fixes the problem. Since the only change in the changelog is the Stack Clash fix and since I remember reading that the JVM does tricky stuff with the stack, this is a natural culprit. It touches any program that initialises a JVM (so for instance Java bindings in Postgresql or Java applets in firefox although the latter have been deprecated and are only supported in firefox ESR now). I attach the repro-case. The issue happens with both openjdk-8-jdk from the repository and the standard jdk 8 from oracle.
