Bugzilla #49733:
Resolved compilation (safe one), Checkstyle and many Javadoc warnings.
Submitted by: Glenn Adams <glenn.at.skynav.com>
Changes to patch:
- Restored the deprecated Graphics2DAdapter method (to be removed after Barcode4J 2.1 is released).
- Restored Renderer.startPageSequence(LineArea) pending discussion about removal.
- build.xml: set max VM to 1024MB instead of 2048MB to allow for 32-bit JVMs.
- build.xml: restored longer taskdef names.
- Restored Checkstyle 4 file for people running older IDEs.
