    JStat -gcutil reporting larger than expected permanent generation in JBoss

    843798
      Why would jstat for -gcutil report about 60% of the permanent generation is in use when the maximum size is at least three times larger that the amount in use? Below are the results of the jstat output. With a maximum PGCMX=262M and a PGC=71M, I was expecting that the percentage in use would be P < 30%

      pbsi:/root> jstat -gcpermcapacity 6003 && jstat -gcutil 6003
