Pressing a dot after typing an instance variable in a Java method body to see its members and other definitions as suggestions is not working currently in eclipse-jdt-ls for Java. While this is working for imports, methods do not get resolved. This commit replaces a suspicious dot that may be related to this, which causes the issue to get fixed.

I believe that there is an error in the way
refresh_patternis set for eclipse-jdt-ls, that prevents complete suggestions to be shown after a dot has been typed (such as using the dot to access the methods of an instance variable).The refresh pattern was originally set in #490. Other issues in vim-lsp and vim-lsp-settings seem to be pointing to this:
As seen in the following case, while suggestions work after typing a dot in the import statement, typing a dot inside a method body does not present suggestions.

Patching the refresh_pattern for eclipse-jdt-ls and removing the dot as proposed in the patch causes dots to always trigger the completion menu, both on imports and on method bodies:

I know little about Vim patterns and their differences in regard to normal PCRE patterns and while the fix seems to work and is aligned with the experience of other people in issues linked above, I'm scared about unexpected consequences of changing this.
