HotSpot VM refuses to start with -Xms2m option on Solaris/SPARC: 

    >>>> .../jdk1.4.0beta-b81/solsparc/bin/java -Xms2m HelloWorld
    Error occurred during initialization of VM
    Too small initial heap for new size specified

    >>>> .../jdk1.4.0beta-b81/solsparc/bin/java -Xms3m HelloWorld
    Hello world!

However, the online documentation says that 2Mb is the default 
value for initial heap size, see:
    http://java.sun.com/j2se/1.4/docs/tooldocs/solaris/java.html

    "...
    -Xmsn 
       Specify the initial size, in bytes, of the memory allocation pool.
       This value must be a multiple of 1024 greater than 1MB.
       Append the letter k or K to indicate kilobytes, or m or M to
       indicate megabytes. The default value is 2MB. Examples: 
    ..."

This citation does not defines: if HotSpot must start with 1025k 
or either 1025k is necessary but may be not enough value for -Xms 
option. However, HotSpot definitely must start with -Xms2m because 
documentation says 2MB is the default value. 

Actually, the minimal enough value is 128k bigger for Merlin 
(I assume, that 1k=1024, and 1m=1024k): 

    >>>> .../jdk1.4.0beta-b81/solsparc/bin/java -Xms2176k HelloWorld
    Error occurred during initialization of VM
    Too small initial heap for new size specified

    >>>> .../jdk1.4.0beta-b81/solsparc/bin/java -Xms2177k HelloWorld
    Hello world!

May be, J2SE online documentation should be updated?
