FULL PRODUCT VERSION :
java version " 1.7.0_25 "
Java(TM) SE Runtime Environment (build 1.7.0_25-b16)
Java HotSpot(TM) Client VM (build 23.25-b01, mixed mode, sharing)


ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.2.9200]

A DESCRIPTION OF THE PROBLEM :
We use heavily webstart apps that are also quite big with loads of jars and jnlps (extensions in extensions and so on)

see for example: https://login.directmanager.nl/servoy-client/DirectManager.jnlp

that jnlp has a reference to for example: it2be-calendar.jar.jnlp
that again has 4 jars, that builds up a calender bean/component

Now if i start with the java console enabled/showing. It works just fine. If i disable or hide the java console through the preferences the bean class can't suddenly be found.

also i see really a difference in the trace.. If it works i see right before the bean is loaded this in the console or output log file:

Missing Permissions manifest attribute for: https://login.directmanager.nl:443/plugins/it2be-calendar/migcalendar.jar
Missing Codebase manifest attribute for: https://login.directmanager.nl:443/plugins/it2be-calendar/migcalendar.jar

that means that that jar is then touched. If the console is disabled those 2 lines don't come up and i get a ClassNotFoundException..



REGRESSION. Last worked in version 7u25

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
i could give you some customers login codes but i can't just give it you through this.

Missing Permissions manifest attribute for: https://login.directmanager.nl:443/plugins/it2be-calendar/migcalendar.jar
Missing Codebase manifest attribute for: https://login.directmanager.nl:443/plugins/it2be-calendar/migcalendar.jar

that is a log file when it works around that same time

This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
no thing found so far except showing the java console which is ofcourse not really doable in a production environment
