Burp 2.0.14 install4j error.log

Seth Jackson Jan 24, 2019 04:20PM UTC

I get an error.log generated when using the Burp 2.0.14 Windows 64-bit installer.

Looks like this happened because the included JRE got updated to Java 11.

How are you launching the installer?

You’re right, we did update the JRE to 11. However we have made sure to include sun.misc.Unsafe, so this shouldn’t happen – and doesn’t happen on our 64-bit Windows systems.

Seth Jackson Jan 25, 2019 02:03PM UTC
I just downloaded the Windows 64-bit installer and double clicked it.

It looks like some modules are missing in the bundled JRE from looking at the other issue with SQLiPy but maybe I'm missing something.

Paul Johnston Jan 28, 2019 03:26PM UTC Support Center agent

We think we know what’s causing this now and it should be resolved in the next beta.

In the meantime, please either use 2.0.13 or the standalone jar.

Seth Jackson Jan 29, 2019 03:02PM UTC
Thanks! This looks to be fixed in 2.0.15.
