Piotrek Żygieło has done many commits for GlassFish (https://github.com/eclipse-ee4j/glassfish/commits?author=pzygielo) and has been doing consistently for a long time. We have never formally invited Piotrek as committer, and this should be high time.
For these reasons and the long-term outlook for their involvement on the team, it is my pleasure to nominate Piotrek Żygieło as a committer on Eclipse GlassFish.
