Reduce plugin dependencies about eclipse.jdt.ls HOT 5 CLOSED

Plugins we could likely get rid of from:

1. /org.jboss.tools.vscode.product
   • org.eclipse.ant.core
   • org.eclipse.debug.core
   • org.eclipse.jdt.launching
   • org.eclipse.jdt.launching.macosx
   • org.eclipse.team.core
2. /org.jboss.tools.vscode.java
   • org.eclipse.jdt.launching

The bigger issue here is that jface.text is used in /org.jboss.tools.vscode.java, which has the side effect of dragging in SWT and a bunch of UI plugins when built.

from eclipse.jdt.ls.

To clarify the previous comment regarding org.jboss.tools.vscode.java and jface.text:
The bundle illegally uses the following internal classes from jface.text:

org.eclipse.jface.internal.text.html.SubstitutionTextReader;
org.eclipse.jface.internal.text.html.SingleCharReader;

from eclipse.jdt.ls.

Fixed the JFace dependency with 05c9c34

from eclipse.jdt.ls.

This change brought the disk footprint down from 86 to 51 MB

from eclipse.jdt.ls.

excluding .gz got us from 51mb to 37mb

launching is still included because org.eclipse.m2e.jdt depends on it. will need to be looked at seperately.

from eclipse.jdt.ls.
