IMPOSSIBLE TraceLine.getMethodLine() not found, and ClassCastException

[Erhannis]

I encountered a set of error messages. First, I received many of the following (slightly anonymized), for a variety of places in the code:

com.lambda.Debugger.DebuggerException: IMPOSSIBLE TraceLine.getMethodLine() not found: 5                             <Logger_344>.callTurboFilters(null, <Level_7>) -> <FilterReply_0>[0]                             callTurboFilters -> <FilterReply_0>[391865]

After many of those, they appeared to stop happening, and instead I got many of the following (in at least a few places):

At some point, I also started getting ODB: GC could not collect enough to continue. Recording turned off.. However, I don't know if that's related.

I tried for quite a while to figure it out, but I don't know ODB's internals well enough to make good headway. (Is there a source of such information?) However, I did notice something that seems suspicious: in TraceLine.getMethodLine(), the VectorD returned from unfilteredTraceSets contained TraceLines whose times were out of order. I don't KNOW if that's unexpected, but it seems odd. I've attached a screenshot. Note the times of 3, 0, and 403584, in that order.
