illegal reflective access operation with 1.3.2 and openjdk11

[cova-fe]

I'm testing rd cli with openjdk11 and I'm seeing this issue, starting from 1.3.2. 1.3.1 is fine.
1.3.2 is fine with openjdk8

It is only a warning, but maybe useful to know.

WARNING: An illegal reflective access operation has occurred

WARNING: Please consider reporting this to the maintainers of retrofit2.Platform
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations

Hi,

I've the same bug with openjdk 11.0.8.
I'm searching for a temporary workaround to hide the error message in shell script : just add a very poor 2>/dev/null like rd projects list --outformat "%name" 2>/dev/null

we can add a jar manifest entry which quells this I believe. reference: square/retrofit#3448
