I am having problem with vscode and jdk, I use it in windows with many configs, but with ubuntu, It brings me this error:

Everything is ok with jdk-default on vscode bash terminal.
jdk bin:
readlink -f $(which java) --> /usr/lib/jvm/java-11-openjdk-amd64/bin/java
jdk version:
java --version
openjdk 11.0.11 2021-04-20
OpenJDK Runtime Environment (build 11.0.11+9-Ubuntu-0ubuntu2.20.04)
OpenJDK 64-Bit Server VM (build 11.0.11+9-Ubuntu-0ubuntu2.20.04, mixed mode, sharing)
but, if I try to found a $JAVA_HOME on terminal, it returns empty.. I do not know more what can I do... already changed other thigns like:
configure.runtime:

json.conf:
If someone could help me with some link, documentations, or anything, thanks!
