Jan Haderka commented on MAGNOLIA-2331:
---------------------------------------
The Workflow/ExpressionStore issue seems like a race condition on startup.
AbstractExpressionStore tries to first call loadExpression() method of the
JCRExpressionStore and if this call fails with exception it will silently
swallow the exception and call storeExpression() method instead. Since each of
the methods obtain hierarchy manager it is possible to get session with pending
changes in the second call. To get more insight we should wrap content of
loadExpression() in the try/catch block and make sure any exceptions are
properly reported.
