[tools-pmc] Committer Election for Jason Koch on Eclipse Memory Analyzer

[emo@xxxxxxxxxxxxxxxxxxxxxx]

A committer election for Jason Koch on project Eclipse Memory Analyzer™
(tools.mat) was started by Krum Tsvetkov with this criteria:

Jason Koch has made a number of very valuable contributions to the Eclipse
Memory Analyzer, the most notable ones being changes to speed-up the
heap-dump parsing process by extensively using parallelism.
Jason started contributing to MAT in 2019 and kept his interest in the
project - making further contribution and actively participating on the MAT
developer mailing list.
He has deep understanding of MAT's code base and valuable ideas on possible
improvements and the future development of MAT.

Here is a list of bugs where Jason was involved and commits (out of the IP
