I see the following exception in NetBeans log if I connect to bluebox.russia (Solaris x86) and type "nano". Terminal stops working after this. java.lang.reflect.InvocationTargetException at java.awt.EventQueue.invokeAndWait(EventQueue.java:997) at javax.swing.SwingUtilities.invokeAndWait(SwingUtilities.java:1320) at org.netbeans.lib.terminalemulator.StreamTerm$OutputMonitor.run(StreamTerm.java:251) Caused by: java.lang.NumberFormatException: For input string: "" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48) at java.lang.Integer.parseInt(Integer.java:470) at java.lang.Integer.parseInt(Integer.java:499) at org.netbeans.lib.terminalemulator.AbstractInterp.numberAt(AbstractInterp.java:155) at org.netbeans.lib.terminalemulator.InterpANSI$InterpTypeANSI$ACT_ATTR.action(InterpANSI.java:342) at org.netbeans.lib.terminalemulator.InterpDumb.processChar(InterpDumb.java:241) at org.netbeans.lib.terminalemulator.Term.putc_work(Term.java:3897) at org.netbeans.lib.terminalemulator.Term.access$400(Term.java:247) at org.netbeans.lib.terminalemulator.Term$BaseTermStream.putChars(Term.java:404) at org.netbeans.lib.terminalemulator.Term.putChars(Term.java:3157) at org.netbeans.lib.terminalemulator.StreamTerm$OutputMonitor$Trampoline.run(StreamTerm.java:200) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:199) at java.awt.EventQueue.dispatchEvent(EventQueue.java:597) at org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:133) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:269) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:184) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:174) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:169) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:161) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122)
This seems to be because of poor handling of malformed escape sequences, but it would help to know what the malformed sequence is. It has to be something of the form <esc> [ <n1> ; m <esc> [ <n1> ; <n1> ; m <esc> [ <n1> ; <n2> ; <n3 ; m and so on. Just typing 'nano' won't do it. what shell are you using? Is emacs or vi cmdline editing turned on? Terminal can echo debugging stuff but there is no trivial way to turn it on from the user level. We might have to add that before we know what the bad sequence is. I can also try a blind fix and see where we go from that.
One other thing ... you might be emitting some terminal control characters with your prompt. For example in bash this is done by setting $PROMPT_COMMAND to some shell function or command.
The control sequence is "[7;m" Exception occurs when InterpANSI.ACT_ATTR.action() loops over ai numbers: 341: for (int n = 0; n <= ai.nNumbers(); n++) 342: ai.ops.op_attr(ai.numberAt(n)); Here ai.nNumbers() == 1, but ai.number[1] == "". Probably the loop should be for (int n = 0; n < ai.nNumbers(); n++)
16d4fdb3d65f - preparatory cleanup of annotations aeca8fa932ae - convenient way to turn on Term debugging. Pass the following to the IDE at startup: -J-DTerm.debug=ops,keys,input,output,wrap,margins Or in nbproject/private/private.properties put run.args.extra=-J-DTerm.debug=ops,keys,input,output,wrap,margins e8fd486b529 - actual fix The <= in the loop is correct. The actual syntax for ESC m is this: <esc> [ <n1> m <esc> [ <n1> ; <n2> m <esc> [ <n1> ; <n2> ; <n3> m ... I either misquoted or quoted from a bad source earlier. This means that the sequence being sent, "<esc> [ 7 ; m" is "poorly formed". There should be no ';' or a number after the ';'. And Term should not throw an exception on this but treat the missing number after the ';' as some default number. For now fixing in AbstractInterp.numberAt() such that it returns a default of 0 in case of trouble.
