Using 6.0 200610231800 on JDK 6.0 RC I get this every time I do a single file build. Sometimes it appears to disable the toolbar button for debug single file until I switch files. java.lang.IllegalStateException: No match found at java.util.regex.Matcher.group(Matcher.java:468) at org.apache.tools.ant.module.api.IntrospectedInfo$3.load (IntrospectedInfo.java:706) at org.apache.tools.ant.module.AntSettings.getCustomDefs (AntSettings.java:112) at org.apache.tools.ant.module.bridge.impl.BridgeImpl$1.run (BridgeImpl.java:268) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:541) [catch] at org.openide.util.RequestProcessor$Processor.run (RequestProcessor.java:963)
