Cross-posting to security-dev as this is more relevant to that list and bcc-ing core-libs-dev.

I think this might be an issue with the JavaWebStart SecurityManager not being granted the proper permissions. It is possible that the deployment policy files are not being loaded or there is some other subtle bootstrapping issue. It should not result in a recursive loop of course, but there may be a workaround.

In the meantime, can you send me more information, preferably a test case and a log file with -Djava.security.debug=all enabled? (The latter will help analyze the recursion and see what security checks are failing and for which ProtectionDomains). Also, have you tested this on builds earlier than b181?

Thanks,
Sean

I should add that we have not modified or overridden any policy files.
Also, we are not using a custom security manager.

Hi,

I hit an infinite recursion loop probably related to PolicyFile that
exists in Java 9 build 181 for windows 64-bit.  It might be related to
JDK-8077418 <https://bugs.openjdk.java.net/browse/JDK-8077418>

I haven't tracked down what is causing our webstart app to hit this
problem yet, but I thought I would let you know sooner than later.  Also,
it probably is not a problem for our particular application as I should be
able to set the security manager to null which I think/hope will bypass
this issue.  I will try today to reproduce it in our app so I can confirm
if setting security manager to null will work for us.
