Hi.
I want to debug elasticsearch 6.3.2 on my win7, and Java version is 10.0.2, I did the following
1. download elasticsearch 6.3.2 source and than unzip it
2. gradlew idea
3. import into idea
4. configure the following variables in the vm option: -Des.path.home, -Des.path.conf, -Dlog4j2.disable.jmx
When running 6.3.2 I got the following exceptions:
