Applets load very slowly on Java 8u 45 with an error, while it works fine with Java 7

I get a Stackoverflow error on the Java console when opening applets over the network in Java version 8 build 1.8.0_45-b15. The applet loads, but takes about 8 minutes, and the same thing works fine in any version of Java 7 over the network.

Can anyone help. The column is as follows.

I have a similar problem and search.

We use the applet in Firefox. Current testing versions:

  • Firefox: 46.0.1
  • Java: jre1.8.0_51 (32bit)

I used JFR (Java Flight Recorder) and Oracle Mission Control to analyze a long freeze (about 5 seconds) when starting our user interface.

So far, I have found that the Permissions.implies() method takes a very long time for an unknown reason.

My analysis showed 2 long blocked stacks for 2 different threads, which both were long (about 2 s and 4 s) in this method.

Here is one call stack allocated by JMC: (for reference: 4.340.000.123ns = 4.34s)
