Due to Hibernate issue HHH-8310 the following error message may appear when defining Blob columns.

java.lang.IllegalArgumentException: interface org.hibernate.engine.jdbc.WrappedBlob is not visible from class loader...

Setting lazy="false" for Blob in service.xml was the key to reproduction, however build-service task failed with this attribute even though it can be set to false according to liferay-service-builder_7_0_0.dtd and liferay-service-builder_6_2_0.dtd for 'Blob' type fields. To overcome this I set it instead manually in the generated portlet-hbm.xml like this:

	<class lazy="false" name="com.liferay.test.model.FileEntryFileuploadBlobModel" table="FOO_FileEntry">

Steps to reproduce

1. Deploy the attached portlet named LPS-42478-Blob-test-portlet-7.0.0.1.war
2. Add LPS-42478-Blob-test-portlet to a page
3. Browse a small file and Upload it

Expected
Uploaded file is listed by the portlet and no error is logged
Result
Porlet doesn't render and below error is logged
