Upgading vaadin 7 to 8.1.4 makes problems

General

Hey folks,
I try to upgrade from latest vaadin 7 to vaadin 8.1.4.
Unfortunately the widgetset is not compiled correctly.
After 86% I get an GC Error.
The log tells me following:

[code]
SEVERE: Widgetset compilation failed

java.lang.OutOfMemoryError: GC overhead limit exceeded

Widgetset compilation finished
[/code]In addtion the compiling process does not stop and shows that it is at 86%.

Another error I have is:

The project was not built since its build path is incomplete. Cannot find the class file for com.vaadin.data.util.converter.Converter$ConversionException. Fix the build path then try building this project But I hope that this will vanish when the widgetset is compiled completely.
I hope you can help me.
If oyu need further Information I will try to provide it.
Thanks and kind regards
Matthias

Hi,
for the OOM error try to increase heap size using
-Dgwt.extraJvmArgs=“-Xmx1024m”
 on command line or
extraJvmArgs
 property in plugin configuration

Hey Marco,
thanks for your answer.
I added the argument this way:
Right click on project → properties → vaadin → additional JVM parameters for widgetset compiler and added your parameter 1 to 1 into the inputfield.
Unfortunately it did not help.
In addtion you can see that there is no vaadin version seleected. This field changes to an empty value every time I close the winow, even when I selected version 8.1.4 and applied the settings.

Hi,
I never used GUI tools to modifiy such configurations.
I think that in your case (but this i just an assumption) in “Additional JVM parameters for widgetset …” field you should only put
-Xmx2048m
.

Which IDE are you using? Eclipse?

Hey,
yes I use eclipse and it seems to work with only the Xmx part.
At leat I got other compiling errors now.
I think I will open another thread for my second problem and if I can"t solve my current error I will start another thread as well.
Thank you very much for your help!!!
