5 years ago I've not been able to reproduce the issue on my system. I have made a change that may correct it, but time will tell. I suspect it is a race issue tied to the number of available cores on a system.
Expected Behavior
After choosing to have the Liabilities section of the budget shown (in the budget properties) this section would appear.
Actual Behavior
jGnash throws a ConcurrentModificationException after the "show liabilities" is enabled in the budget properties dialogue. java.util.ConcurrentModificationException: java.util.ConcurrentModificationException at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.base/java.lang.reflect.Constructor.newInstance(Constructor.java:488) at java.base/java.util.concurrent.ForkJoinTask.getThrowableException(ForkJoinTask.java:587) at java.base/java.util.concurrent.ForkJoinTask.reportException(ForkJoinTask.java:668) at java.base/java.util.concurrent.ForkJoinTask.invoke(ForkJoinTask.java:726) at java.base/java.util.stream.ReduceOps$ReduceOp.evaluateParallel(ReduceOps.java:919) at java.base/java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:233) at java.base/java.util.stream.ReferencePipeline.collect(ReferencePipeline.java:511) at jgnash.ui.budget.BudgetPanel.getSparkLineIcon(BudgetPanel.java:637) at java.base/java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:195) at java.base/java.util.ArrayList$ArrayListSpliterator.forEachRemaining(ArrayList.java:1494) at java.base/java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:484) at java.base/java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:474) at java.base/java.util.stream.ReduceOps$ReduceTask.doLeaf(ReduceOps.java:952) at java.base/java.util.stream.ReduceOps$ReduceTask.doLeaf(ReduceOps.java:926) at java.base/java.util.stream.AbstractTask.compute(AbstractTask.java:316) at java.base/java.util.concurrent.CountedCompleter.exec(CountedCompleter.java:747) at java.base/java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:283) at java.base/java.util.concurrent.ForkJoinTask.doInvoke(ForkJoinTask.java:395) at java.base/java.util.concurrent.ForkJoinTask.invoke(ForkJoinTask.java:725) at java.base/java.util.stream.ReduceOps$ReduceOp.evaluateParallel(ReduceOps.java:919) at java.base/java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:233) at java.base/java.util.stream.ReferencePipeline.collect(ReferencePipeline.java:511) at jgnash.ui.budget.BudgetOverviewPanel.lambda$updateSparkLines$3(BudgetOverviewPanel.java:183) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1167) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641) at java.base/java.lang.Thread.run(Thread.java:844) Caused by: java.util.ConcurrentModificationException at java.base/java.util.ArrayList$ArrayListSpliterator.forEachRemaining(ArrayList.java:1500) at java.base/java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:484) at java.base/java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:474) at java.base/java.util.stream.ReduceOps$ReduceTask.doLeaf(ReduceOps.java:952) at java.base/java.util.stream.ReduceOps$ReduceTask.doLeaf(ReduceOps.java:926) at java.base/java.util.stream.AbstractTask.compute(AbstractTask.java:316) at java.base/java.util.concurrent.CountedCompleter.exec(CountedCompleter.java:747) at java.base/java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:283) at java.base/java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1603) at java.base/java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:175)
