IllegalArgumentException Unknown pattern character 'X' on version 1.6.

[masahiro-ikemoto]

On version 1.6,

java.lang.IllegalArgumentException: Unknown pattern character 'X'

was thrown from com.microsoft.graph.serializer.CalendarSerializer.deserialize() method on Android 6 or prior devices.

It caused by using SimpleDateFormat pattern charactor 'X' is supported from java 7 but device has java 6 VM.

CalendarSerializer didn't use 'X' pattern before version 1.5.

Would you like to rewrite CalendarSerializer.deserialize() method using no 'X' charactor?

Thanks for reporting this issue. We're looking into this.

Hello!
So, is there any progress on this issue?
I used graph-android and I'm planning to migrate to graph-java (because graph-android apparently no longer supported).
But I still have this problem at 1.7.1. Because of it I can’t migrate =(

Hi!
Im having the same problem when trying to create an UploadSession at 1.7.1 version.

UploadSession us = mClient
.sites().byId(siteIdI)
.drives().byId(driveIdI)
.items().byId(folderId)
.itemWithPath("_hamilton.pdf")
.createUploadSession(new DriveItemUploadableProperties())
.buildRequest()
.post();

ClientException: Error during http request
Caused by: IllegalArgumentException: Unknown pattern character 'X'

I also run into this issue and had to downgrade to 1.5.0 ...

Hi everyone,
Thanks for this question and for your patience.
You should be able to get support for this pattern character through desugaring as it adds support for patterns

We're looking at bumping the java version to 1.8 with the next major version of this lib so we stay on a supported set of tooling and eco-system. The service replies with offsets in the payload. So we won't be removing this character.
I'll be closing this question as it's old. But feel free to comment on it and I'll re-open it if needs be.
