OSGi compatibility + SVGProviderInfo classloader lookup

See original GitHub issue

Although TwelveMonkey is not OSGi-ready, it is relatively easy to port it to OSGi by SPI-fying it using an approach similar to what demonstrated in: https://github.com/Maurice-Betzel/twelvemonkeys-osgi.

However, the call to isClassAvailable on https://github.com/haraldk/TwelveMonkeys/blob/633e5cc6a2c0637e508ab334b629b24470071724/imageio/imageio-batik/src/main/java/com/twelvemonkeys/imageio/plugins/svg/SVGProviderInfo.java#L42 prevents OSGi from finding SVG reader (as it returns false). Removing line 42 makes SVG reader available and SVG parsing works fine.

So, is this classloader lookup absolutely necessary, if not could it be removed in a future version?

Thanks.

Hi Harald, didn’t know GitHub could detect a comment in another project’s commit and cross-post back to the original project/issue being mentioned 😃 The patch was for our own project in which we needed a solution immediately, I understand it’s not a solution in general for TM.

I still intend to test your proposal, it sounds like it could solve the problem. Give me a couple of days and I’ll get back to this.

Implemented. Feel free to reopen the case, should you test and find it does not solve the issue.
