I'm looking for a way to break into the debugger from Java code, without setting a breakpoint in the IDE.
In Win32 there was DebugBreak(), in C# there's DebugBreak() Equivalent in C#, but I can't find anything in Java.
What I'm trying to do: say I have a wait with a 30s timeout, but in normal conditions that wait should always be <1s. I'd like to use ByteMan or something similar to wait with 1s timeout first, and break into the debugger if that wait timed out.

The Java Debugger, jdb, is a simple command-line debugger for Java classes. It is a demonstration of the Java Platform Debugger Architecture that provides inspection and debugging of a local or remote Java Virtual Machine.
View and configure breakpointsThe Breakpoints window lets you enable or disable each breakpoint from the list on the left. If a breakpoint is disabled, Android Studio does not pause your app when it hits that breakpoint. Select a breakpoint from the list to configure its settings.
Not a direct answer to your question but in most IDE's you can set conditional breakpoints.
This would require you to set a timestamp variable in your code before the timeout and test its value in your breakpoint, after the timeout. You would trigger your breakpoint conditional if the delta is greater than your threshold.

The poster of this question has done exactly what I was looking for: Secure Debugging for Production JVMs
It reproduces the best feature of DebugBreak, that is you can attach the IDE to your program only after the "breakpoint" is hit.
