<div>Hello Mattias,</div>
<div> </div>
<div>thank you for your quick reply. I tried with classpath 0.99. But without success.</div>
<div>I also checked the savannah cvs and the files you mentioned have not changed the last few years.</div>
<div>Do you have any other ideas?</div>

<p class="MsoNormal"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">I have the following Java Code which in my opinion causes a memory leak in jamvm.<br/>
It could be programmed better, but in my case I want to run the eclipse equinox OSGi<br/>
framework and sometimes the kernel kills jamvm because there is no memory left. I<br/>
reduced the code until this sample remains:<br/>
public class HelloWorld {<br/>
public static void main(String[] args) {<br/>
while(true) {<br/>
Float f1,f2;<br/>
Float fRes;<br/>
String sRes;<br/>
f1 = 23.4f;<br/>
f2 = 2.5f;<br/>
fRes = f1 * f2;<br/>
sRes = Float.toString(fRes);<br/>
}<br/>
}<br/>
}</span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">Running this code with a diffrent JRE or even with the ubuntu jamvm works fine.<br/>
Only with my compiled jamvm version 1.6.0 and classpath 0.99 the memory usage is very high and the kernel keeps killing the jamvm process.<br/>
Any suggestions what could be done?</span></p>
