Resolved: java.lang.OutOfMemoryError: Java Heap space

When opening a large heap file, the following error occurs.
java.lang.OutOfMemoryError: Java Heap space
at com.ibm.jinwoo.heap.HeapInfo.readHAX(HeapInfo.java: 8319)
...

Solution
It would be resolved by increasing the memory for the Heap Analyzer by the following command.

java -Xmx1024m - jar ha454.jar

if it is not enough, you can try to adjust to -Xmx2048m or -Xmx4096m
