Error when using CollectWgsMetrics on Picard

Hello, i was running CollectWgsMetrics with a BAM file as input and when it finished running it showed the following message:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 248956422
at picard.analysis.AbstractWgsMetricsCollector.isReferenceBaseN(AbstractWgsMetricsCollector.java:215)
at picard.analysis.WgsMetricsProcessorImpl.processFile(WgsMetricsProcessorImpl.java:92)
at picard.analysis.CollectWgsMetrics.doWork(CollectWgsMetrics.java:491)

at picard.cmdline.PicardCommandLine.instanceMain(PicardCommandLine.java:103)
at picard.cmdline.PicardCommandLine.main(PicardCommandLine.java:113)

Do you have any idea why?
Thank you,
Francisco
