Profiling is unstable when using LaunchWrapper

Something LaunchWrapper does breaks profiling (not sampling), and sometimes causes everything to freeze. This mainly causes issues with profiling Minecraft modifications. It's likely to be an issue with LaunchWrapper as I don't remember it ever working reliably with profiling, but it seems like it got much worse in 1.4.1. Also note that LaunchWrapper does NOT work with java 9 and above.

When trying to start profiling when the application is already running, it sometimes works but most of the time (especially when profiling all classes) it the application will stop responding. When using startup profiling, it will almost always freeze at some point, usually in the same place, when loading some class.

I was able to reproduce the issue just by wrapping an existing project that I could profile without any issues in LaunchWrapper, but no matter what small synthetic test I came up with, everything worked fine. So this means I don't have a small test case that reproduces the issue.

This is example thread dump I got when it froze: https://pastebin.com/raw/Zfw7ZWss

Start by reproducing profiling with a project wrapped in LaunchWrapper, comparing startup profiling with profiling an already running application. Review the provided thread dump when the application freezes and determine whether the failure is specific to LaunchWrapper or VisualVM. Done means the cause is isolated and profiling no longer intermittently freezes the wrapped application.
