Hi, before I go too far in destroying my machine :-) I had jPSKmail 1.5.10 running fine while I was on holiday using; java version "1.7.0_25" OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.12.04.2) OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode) But when I tried to run a fairly recently downloaded version 2 I get the following error messages (I have left the *.jar in the directory it was dropped into by the archive manager by the way but I run the package from the directory); gregm@rover:~/Downloads/home/rein/jpskmail$ java -jar javapskmail2.jar Stable Library ========================================= Native lib Version = RXTX-2.2pre2 Java lib Version = RXTX-2.1-7 WARNING: RXTX Version mismatch Jar version = RXTX-2.1-7 native lib Version = RXTX-2.2pre2 Exception in thread "SoundInput" java.lang.IllegalStateException: Mixer is already open at org.classpath.icedtea.pulseaudio.PulseAudioMixer.openImpl(PulseAudioMixer.java:650) at org.classpath.icedtea.pulseaudio.PulseAudioMixer.openLocal(PulseAudioMixer.java:588) at org.classpath.icedtea.pulseaudio.PulseAudioMixer.openLocal(PulseAudioMixer.java:584) at org.classpath.icedtea.pulseaudio.PulseAudioMixer.open(PulseAudioMixer.java:579) at org.classpath.icedtea.pulseaudio.PulseAudioDataLine.open(PulseAudioDataLine.java:94) at org.classpath.icedtea.pulseaudio.PulseAudioTargetDataLine.open(PulseAudioTargetDataLine.java:111) at org.classpath.icedtea.pulseaudio.PulseAudioTargetDataLine.open(PulseAudioTargetDataLine.java:130) at javapskmail.SoundInput.run(SoundInput.java:76) jPSKmail ends here... Exception in thread "main" java.lang.NumberFormatException: For input string: ";" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65) at java.lang.Integer.parseInt(Integer.java:492) at java.lang.Integer.parseInt(Integer.java:527) at javapskmail.Icons.getIconImage(Icons.java:44) at javapskmail.Mainpskmailui.<init>(Mainpskmailui.java:209) at javapskmail.Main.main(Main.java:401) I had a quick look through the archives etc. but couldn't immediately find any recommendation whether the openJDK was still acceptable or whether I have to use the Oracle version instead. What have I done wrong? :-) 73, Greg, G0DUB
