My work around is to create a pipeline wrapper class that has a run(JCas)
method and that seems to work fine. But I would still like to know what is
causing the issue. It is effectively doing this under the hood, which is
fine.
piperReader.loadPipelineFile("path/to/default.piper");
piperFileReader.getBuilder().set(UmlsUserApprover.KEY_PARAM, "<key>");
piperFileReader.getBuilder().build();
SimplePipeline.runPipeline(jCas,
piperFileReader.getBuilder().getAnalysisEngineDesc());
