> New JVMTI function `ClearAllFramePops` will help to speedup debugger single > stepping in some cases. > Additionally, the JVMTI `NotifyFramePop` implementation was fixed to return > `JVMTI_ERROR_DUPLICATE` to make it consistent with the `SetBreakpoint` which > also returns this error. > > The JDWP agent fix will be needed to make use of this new JVMTI function. The > corresponding debugger bug is: > [8229012](https://bugs.openjdk.org/browse/JDK-8229012): When single stepping, > the debug agent can cause the thread to remain in interpreter mode after > single stepping completes > > CSR: [8346144](https://bugs.openjdk.org/browse/JDK-8346144): add > ClearAllFramePops function to speedup debugger single stepping in some cases > > Testing: > - mach5 tiers 1-6 were run to make sure this fix caused no regressions > - Chris tested the JVMTI patch with his JDWP fix of > [8229012](https://bugs.openjdk.org/browse/JDK-8229012).
