SHORT SUMMARY: When several signed applets are simultaneously loaded from the same web page, some of them may not get full permissions. INDICATORS: Different kinds of AccessControlException's that are not supposed to be thrown for signed applets (for example, on reading "user.home" property, or on accessing a local file system). TRIGGERS: The problem happens sporadically and have symptoms of a race condition with low-to-medium failure rate. KNOWN WORKAROUND: Though there is no direct relation between this change and the problem's root cause, disabling the Java Deployment Cache helps to avoid the problem. PRESENT SINCE: Introduction of plugin2, at least. HOW TO VERIFY: There is no stand-alone test case for this issue. The customer verifies the provided binaries in their environment and informs us about the verification results. REGRESSION: No.
