Re: Type system commit race condition when maven builds jar(?)
The issue arose from using the Maven Assembly Plugin to naively build an executable jar with uimaFit components. Files supplied by different dependencies overwrote each other during packaging and some types could not be detected at runtime. The uimaFit documentation has this issue recorded in chapter 9: https://uima.apache.org/d/uimafit-current/tools.uimafit.book.html#ugr.tools.uimafit.packaging <https://uima.apache.org/d/uimafit-current/tools.uimafit.book.html#ugr.tools.uimafit.packaging>. We resolved the issue using the Maven Shade Plugin as shown in the document.

Type system commit race condition when maven builds jar(?)
I am working with UIMA-Alpha02 and am currently trying to build a jar to make a standalone application.
