问题 Experimenting with memory pool pre-allocation, I found that allocating a 60M Float32Array makes sometimes crash the browser tab (tried in Chrome): var bigArray = new Float32Array(60000000) for (var i = 0; i < bigArray.length; i+=1) { bigArray[i] = Math.random() } I'm allocating 240MB in total (i.e. Float32Array.BYTES_PER_ELEMENT * bigArray.length) on an 8Gb machine. That makes the tab crash 20% of times, and 100% if I try to inspect bigArray (e.g., try to get bigArray.length in console, log

问题 I have a webbrowser which is in portrait mode.

Now I want to be able to click on such a report in my Java application and have it displayed in the browser. I already wrote the handler and the correct URL is determined. On my Windows system this is file://localhost/C:/report.xml The XML is not the problem. If I open it manually in my browser everything works fine.

问题 I have an aplication wich I use to register some items.
