// The proxy JNI needs to be created by the browser. If it is created by
|
|
// someone else (e.g., a plugin) on a different thread, the proxy JNI will
|
|
// not work, and break LiveConnect.
|
|
// Currently, on Unix, when instantiating a Java plugin instance (by calling
|
|
// InstantiateEmbededPlugin() next), Java plugin will create the proxy JNI
|
|
// if it is not created yet. If that happens, LiveConnect will be broken.
|
|
// Before lazy start JVM was implemented, since at this point the browser
|
|
// already created the proxy JNI buring startup, the problem did not happen.
|
|
// But after the lazy start was implemented, at this point the proxy JNI was
|
|
// not created yet, so the Java plugin created the proxy JNI, and broke
|
|
// liveConnect.
|
|
// On Windows and Mac, Java plugin does not create the proxy JNI, but lets
|
|
// the browser to create it. Hence this is a Unix-only problem.
|

//
|

// The root cause of the problem is in Java plugin's Unix implementation,
|
|
// which should not create the proxy JNI.
