Martin Leitner commented on FOP-3172:
-------------------------------------
Thanks [~peterhull90] for the analysis! I totally agree that this is what is
going on.
I do not see why there would be no simple way to avoid that.
I suggest to change line 420 in
{color:#000000}{color:#000000}FopFactoryBuilder{color}{color}${color:#000000}{color:#000000}FopFactoryConfigImpl{color}{color}
from
{color:#000000}{color:#7f0055}this{color}{color:#000000}.{color}{color:#0000c0}imageManager{color}{color:#000000}
= {color}{color:#7f0055}new{color}{color:#000000}
ImageManager({color}{color:#7f0055}new{color}{color:#000000}
ImageContextImpl({color}{color:#7f0055}this{color}{color:#000000}));{color}{color}
to
{color:#000000}{color:#7f0055}this{color}{color:#000000}.{color}{color:#0000c0}imageManager{color}{color:#000000}
= {color}{color:#7f0055}new{color}{color:#000000}
ImageManager({color:#000000}{color:#7f0055}new{color}
ImageImplRegistry(){color}, {color}{color:#7f0055}new{color}{color:#000000}
ImageContextImpl({color}{color:#7f0055}this{color}{color:#000000}));{color}{color}
> image-loading configuration settings are not thread-safe

> Key: FOP-3172
> URL: https://issues.apache.org/jira/browse/FOP-3172
> Project: FOP
> Issue Type: Bug
> Components: image/unqualified
> Affects Versions: 2.9
> Reporter: Martin Leitner
> Priority: Major
> Attachments: fop_3172.zip
>
>
> As a workaround for FOP-3171 I added an <image-loading> section to the config
> and noticed that the settings will take effect on all subsequent renderings
> in the same VM, even when they use a different config or none at all. When
> running two or more rendering processes with different configs in parallel,
> the result will basically be random.
> At the very least, this behaviour should be documented and warned about.
