I found that running large queries will cause an internal error due to java heap space. After a long search I found a java plug-in with parameters for use at the command line. I took a leap and tried it with studio and it worked. I no longer have java heap space errors. I feel it may be beneficial to others to have this information and to publish command line arguments for others. Below is the command line I used:
"Apache Directory Studio.exe" -vmargs -Xms512m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=128m Regards Bruce
