IdP 3 strange startup delay

[Youssef GHORBAL]

Hello,

	I’m facing a strange stratup delay on an IdP 3.2.1 runnning on a CentOS 7 (OpenJDK 8) inside a jetty-9.3.8.v20160314.
	The startup process stops for ~40 seconds at "Parsing configuration for attribute filter policy: DefaultPasteurAttributes”
	Here’s the log section :

	As you can see there is a gap of ~40s between “[net.shibboleth.idp.attribute.filter.spring.impl.AttributeFilterPolicyParser:84]” and "[net.shibboleth.idp.attribute.filter.spring.impl.AttributeRuleParser:97]”

	This behaviour is systematic and the “pause” time ranges from ~30s to ~60s

	I’m already @DEBUG log level, how can I dig further ? What can make it take so long at that step ?
	
	I’ll test with an “empty” attribute-filter.xml file and comment further.
