out of memory error, depneds on static object in XMLSeignature?

[Matteo Artuso <ma...@unimaticaspa.it>]

Hi, 
    I verify after 2 signature verification fail in a big xml (500kb), program explode in an java.lang.OutOfMemofyError.
I redefine object XMLSecurity every time into verfing cicle and call System.gc to clear memory, unfortunally, I can't solve the problem.
Probably because there's a static method in XMLSignature and so garbage collector can't clear it.
Any suggestions?

Hello,
try:
-- --
C:\>java -X -?
    -Xmixed           mixed mode execution (default)
    -Xint             interpreted mode execution only
    -Xbootclasspath:<directories and zip/jar files separated by ;>
                      set search path for bootstrap classes and resources
    -Xbootclasspath/a:<directories and zip/jar files separated by ;>
                      append to end of bootstrap class path
    -Xbootclasspath/p:<directories and zip/jar files separated by ;>
                      prepend in front of bootstrap class path
    -Xnoclassgc       disable class garbage collection
    -Xincgc           enable incremental garbage collection
    -Xbatch           disable background compilation
    -Xms<size>        set initial Java heap size
    -Xmx<size>        set maximum Java heap size
    -Xss<size>        set java thread stack size
    -Xprof            output cpu profiling data
    -Xrunhprof[:help]|[:<option>=<value>, ...]
                      perform JVMPI heap, cpu, or monitor profiling
    -Xdebug           enable remote debugging
    -Xfuture          enable strictest checks, anticipating future default
    -Xrs              reduce use of OS signals by Java/VM (see documentation)

The -X options are non-standard and subject to change without notice.
++ ++

Take note of the -Xms and -Xmx - these are the parameters that affect the amount of heap jvm uses.  By defaults it is 64Mb, which in many cases is _not_ enough.  This is the reason for the out of memory failure.

Regards
