javac invocation causes kernel panic @ linux-image-3.13.0-155-generic

[Tom Schnittke]

Dear all,

following situation:

* @AWS i've created a VM using the AMI-Image ami-047c33b824c3c615d
* downloaded the official Oracle JDK 1.8.181 (jdk-8u181-linux-x64.tar.gz)
* as root started "javac" to compile a HelloWorld.java

- as a result the machine became unavailable, i assume , the javac invocation produces a kernel panic and the VM resets.
(since the AWS lacks KVM-console or similar, i cannot see what happens on the terminal)

To reproduce:
1. create a 64bit VM using ami-image ami-047c33b824c3c615d
2. download the Oracle JDK 1.8.181 (jdk-8u181-linux-x64.tar.gz) and extract
3. as root launch "javac" (no ".java" files to compile are really necessary, even the invocation of "javac" binary is sufficient to reset the machine.)

It does NOT happen with e.g. Kernel "linux-image-3.13.0-151-generic".

VM data:

3) No VM reset happens
4) VM resets

I've also tried it @ a local vagrant machine - the behavior here is slightly different -
the "javac" does NOT freezes/resets the machine, but if i compile something, e.g. an elementary "HelloWorld.java", it does NOT procuces a ".class" file, quitting silently.

I get following strace output launching "javac" as described:
