#5 java.lang.OutOfMemoryError: Java heap space

[Anonymous]

CE 2.23 consumes lots of many especially if the class contains many methods. It probably does too many data coping in the GUI.

I tried using CE to view com\sun\tools\javac\comp\Attr.class, which can be found in JDK\lib\tools.jar, it ran out of memory even if I used x64 JDK with 5G of RAM.

C:\Users\samn\Desktop\ce2.23>"c:\Program Files\Java\jdk1.6.0_23\bin\java.exe" -Xmx5000m -Xms5000m -jar ce.jar

Sorry forgot to mention, after open the file, click to "Methods", then it will throw OOM exception.
