Cannot register 'java.home'. This property is already registered

Type: Bug

Keeping pops out "Cannot register 'java.home'. This property is already registered", and the project indexing stays at 0% forever. Tried uninstall and clear cache, but didn't work

You likely have another vscode extension registering the java.home property. So try to disable other extensions until you find it

It seems like this error doesn't matter about the indexing, but for some reason, my indexing is stuck at 0% (Syncing stage) forever.

The indexing issue is fixed by disabling HTTP/2
