Over many years Alexander has been doing an amazing job supporting AspectJ.
Staying completely on top of stack overflow related questions (https://stackoverflow.com/users/1082681/kriegaex ) and raising high quality bug reports (his comment history on AJDT goes back about 10 years). More recently, he has actively been contributing to our projects, both AspectJ and the Eclipse AJDT project. He has been the only person actively looking at AJDT issues recently, and due to the complexity of how AJDT is implemented it is quite fragile as the Eclipse platform itself is updated. Even though he has no OSGi or eclipse plugin background he recognizes it is vital to keep the tooling working and, importantly, with the new found frequency for Java releases we need to drive AspectJ updates into AJDT on a more regular basis.
For these reasons I'd like to nominate him as a committer on Eclipse AJDT.
(Previously this nomination failed due to inactive committers. Hopefully that has been addressed now)
