Description
Remote debugging (for applets in a browser) is no longer working as it did work for 7u15 before, i.e. unable to connect to a JVM with Eclipse since 7u21 and 7u40 latest build.

Normally using the following JRE runtime parameters in the Java control panel allows us to connect remotely to debug the JRE:

��         -Djava.compiler=NONE -Xnoagent -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n


This worked in JRE 7u15, and has not worked since then. The only difference in tests is the JRE version, same browser, eclipse and applet.

one post of someone else having the same issue, is this something that has changed as part of the security as well? How can we once again debug applets using Eclipse?

Here is the post of someone reporting a similar issue.

justification: serious regression since 7u21. developer cannot debug applets with debugger.
