Created attachment 132578 [details] screenshot of blank unresponsive Base and JRE Required This sounds like bug 72397 but that claims to be VERIFIED FIXED, so... ?? I wanted to create an address book database. So from Windows 10 start menu I started LibreOffice Base. LibreOffice Document Recovery warned that it found a .odt file and offered to recover it. I chose [Start] to allow this, so now I have a LibreOffice Writer document open. Again I started Base. (Now I'm remembering what appeared as best I can.) A Database Wizard appeared.I left the default Create a new database, the only choice was HSQLDB Embedded, then Next>> and chose Yes, register the database for me, and checked Open the database for Editing and Create tables using the table wizard. Then [Finish] and It prompted me to save the file, I did so as TestAddressBook. Then a blank window titled "TestAddressBook.odb - LibreOffice Base" appeared, and immediately an alert title "JRE Required" on top of that. I'm 90% sure I don't have any Java runtime installed. No content in either window. I closed the "JRE Required" with the Windows [X] icon, but then it reappeared, this time showing "(not responding)". The LibreOffice Writer window is also unresponsive. The cursor in any of these windows is a a blue circle (a non-animating busy icon?). I tried right-clicking the LibreOffice Base icon in the Windows task bar and choose "Close All Windows", and nothing happened. I just tried it again and now Microsoft prompts "LibreOffice is not responding". In Task Manager I have three "Apps" running under LibreOffice (32 bit) (3): JRE Required, TestAddressBook.odb - LibreOffice Base (Not Responding), and [restored file].odt - LibreOffice Writer (Not Responding). Under Background processes I have three LibreOffice (32 bit) processes , and two LibreOffice Base (32 bit) processes. None using any CPU. I attach a screenshot showing the Base window and alert (the .odt was on my other screen). At times Windows warned that the application wasn't responding, asking if I should close it or wait, I always chose wait. Interestingly after taking the screenshot I again right-clicked the LibreOffice Base icon in the Windows task bar and choose "Close All Windows", and all three windows and both taskbar icons went away. I just repeated all the steps above (this time creating TestBaseHang.odb) and again the blank Base window and JRE Required windows appeared together with the recovered .odt file. This time I was not able to click [X] to dismiss the JRE Required window and I don't see the blue circle cursor (just a pointer), but all three windows are similarly unresponsive. Maybe the table wizard requires JRE?
Yes using Base still requires Java runtime environment, eventually the move to FireBird as default should remove need for enabling a JRE--but for now still required on the Windows builds. Please install a 32-bit JRE [1] and retest. Note: the JRE will need to match the LibreOffice build flavor 32-bit or 64-bit, and will need to be selected active from the Tools -> Options -> Advanced dialog. =-ref-= [1] http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html
Created attachment 132595 [details] alert when I visit Tools > Options> Internet > MediaWiki I should see something like this instead of a blank white window when I try to use Base features that require Java.

OK, so the bug here is that Base doesn't tell you this, I changed the bug title. I can't recommend LibreOffice to normal users if trying to use a default part of the install will appear to work but then hang LibreOffice, display blank windows, and give no information on the solution to the problem but a confusing "JRE Required" window title. Instead Base must check for a JRE and display a user-friendly diagnostic, ideally with a [Help] or other link to more information. Maybe Base is trying to display such an alert, I'm not sure why the "JRE Required" window is blank and unresponsive (see screenshot). > Please install a 32-bit JRE [1] and retest. This bug is not about whether I can make Base work, again it's about the default behavior of LibreOffice. > Note: the JRE will need to match the LibreOffice build flavor 32-bit or > 64-bit,and will need to be selected active from the Tools -> Options > -> Advanced dialog. > > =-ref-= > [1] http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html Awesome info thanks, it needs to be in the LO System Requirements and Release Notes pages, and a Google search for "LibreOffice JRE Required" should find it. I'll file a separate bug.
