@tijs I updated my example to flowable 6.4.1 but the problem is stell present
@tijs When I change the classloading behaviour in org.flowable.common.engine.impl.javax.el.ExpressionFactory (line 112) from
classLoader = Thread.currentThread().getContextClassLoader();
classLoader = ExpressionFactory.class.getClassLoader();
everthing works as expected. Is there any chance to get rid of the ContextClassLoader?
I came around this issue by setting the ContextClassloader in a CommandInterceptor:
Ideally, the org.flowable.osgi.blueprint.ProcessEngineFactory.init() Method would do this, so this issue would be solved for everybody using OSGi
