SQLiPy fails to load after upgrade to v2.0.14beta

| Last updated: Jan 24, 2019 01:39AM UTC

After upgrading to BurpSuite v2.0.13beta the SQLiPY extension fails to load with the following error: ImportError: signal module requires sun.misc.Signal, which is not available on this platform After rolling back to v2.0.13beta SQLiPY extension is able to be loaded again.

This will be fixed in the next beta release of Burp. In the meantime, Seth's workaround is great!

I think this is happening because the bundled Burp JRE has been updated to Java 11. JDK 9 encapsulated sun.misc.Signal (and other stuff) inside the 'jdk.unsupported' module and my guess is something is going wonky with the class/module loading. Interestingly enough if I launch Burp using my own JDK 11 instead of using the bundled Java 11 JRE and I launch Burp using 'java -jar <path to Burp jar>' I can load the extension just fine. JAVA_HOME is set to my own JDK 11 and here is the output of 'java -version': openjdk version "11.0.1" 2018-10-16 OpenJDK Runtime Environment 18.9 (build 11.0.1+13) OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode) Bundled JRE 'java -version': openjdk version "11.0.1" 2018-10-16 OpenJDK Runtime Environment 18.9 (build 11.0.1+13) OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)

So I figured out why this is happening. The default JDK download from Oracle contains more modules than the bundled JRE does. You can list the modules with --show-module-resolution when launching Burp from the jar. Basically the bundled JRE doesn't ship with the jdk.unsupported module so the class fails to load.

Thanks Seth, I'll try running with the JDK.
