Bug 317878

Description Len Tyson 2010-06-24 16:05:05 EDT

Build Identifier: 20100218-1602

Description: Open Hibernate3 tutorial. Double click 'hibernate.cfg.xml'. Receive NPE

<quote>
The troublemaker entry is /hibernate-distribution-3.5.2-Final.pom which starts with '/' while usually all file entries in the root of jar do not have it as leading symbol. I can easily modify my code to check for it, but it seems that Eclipse itself is not happy about it. Find hibernate3.jar Package Explorer under libraries of a project, navigate to hibernate-distribution-3.5.2-Final.pom and try to open it. Editor fails. So, what should we do. May we ask provider of hibernate3.jar to modify the entry path as erroneous, or should we report to Bugzilla on Eclipse failure to process such entries?
