[dominee]

Description:

Elastic Exporter does not start. The button remains blue, labeled "Starting Elastic Explorer" while burpsuite throws the following exception:

Providing libraries via burp extension configuration or launch options had no effect.

java -cp jackson-core-2.15.3.jar -cp jackson-databind-2.15.3.jar -cp elasticsearch-java-8.10.3.jar -jar burpsuite_pro_v2023.10.2.2.jar

Steps To Reproduce:

1. Configure Elastic Exporter
2. Click "Start Elastic Exporter"

Expected behavior:

Elastic exporter starts and exports the logs.

Version:

Logger++: 3.20.0
Elastic : 7.5.0 (as stated in issues/157 )
BurpSuite: v2023.10.2.2 (and v2023.10.1.x)
OS: macOS Ventura 13.5.1 (22G90)
JDK: openjdk version "20" 2023-03-21

The issue was observed on MacOS Ventura 13.5.1 (22G90) using Homebrew Openjdk, but is present in the bundled version as well. Also confirmed to be not working on other MacOS installations/devices.

openjdk version "20" 2023-03-21
OpenJDK Runtime Environment Homebrew (build 20)
OpenJDK 64-Bit Server VM Homebrew (build 20, mixed mode, sharing)

Thank you in advance for your help.

Thanks for the report, looking into this now

Unfortunately, the Elastic API doesn't have any backwards compatibility so when #157 is merged into master Elastic 7.x will be unsupported. I'll close this issue for this reason and use #157 to track the reintegration of Elastic exports.
