Applets intermittently not sharing VM context in JRE 7u4+
We have an application that requires that multiple applets be able to communicate - ie. share a single VM instance (java.exe). This seems to work fine in JRE 6u32, but after installing JRE7u4+ this no longer works reliably, with multiple instances of Java.exe intermittently being created and as a result our applets are not able to communicate as required. This occurs even if we specify a java_version in our applet tags (1.6*) with the only workaround being to completely uninstall java 7. It also occurs whether we build against JDK6 or JDK7.
Has applet context sharing changed in Java 7 that would explain this behaviour? Any assistance with how we can resolve this issue would be greatly appreciated.
